I am implementing the petstore API with openAPI in a (gradle) spring boot project. I generate a server with the openapi generator plugin and implement a simple request:
```java
@Service
@RestController
public class PetApiController implements PetApi {

    @Override
    public ResponseEntity<Pet> getPetById(Long petId) {
        Pet p = new Pet();
        p.setId(0L);
        p.setName("fido");
        p.setPhotoUrls(new ArrayList<String>());
        p.setStatus(StatusEnum.AVAILABLE);
        p.setTags(new ArrayList<Tag>());
        Category c = new Category();
        c.setId(3L);
        c.setName("dummy category");
        p.setCategory(c);

        ResponseEntity<Pet> r = new ResponseEntity<Pet>(p, HttpStatus.OK);

        return r;
    }
}
```
The swagger-ui that I generate offers both xml and json queries for a request, but xml doesn't seem to work:
```bash
$ curl -X GET "http://localhost:8080/pet/1" -H  "accept: application/xml"; echo ""

$ curl -X GET "http://localhost:8080/pet/1" -H  "accept: application/json"; echo ""
{"id":0,"name":"fido","category":{"id":3,"name":"dummy category"},"photoUrls":[],"tags":[],"status":"available"}
```
Why is this happening?
when Using start.spring.io projects generated with springboot 2.7 comes with MavenProject 3.8.5 which when imported in intellij causes an error that is quite difficult to debug or not self speaking by itself.

The error:

I've created a new Java project in IntelliJ with Gradle that uses Java 17. When running my app it has the error Cause: error: invalid source release: 17.

My Settings

I've installed openjdk-17 through IntelliJ and set it as my Project SDK.
The Project language level has been set to 17 - Sealed types, always-strict floating-point semantics.
In Modules -> Sources I've set the Language level to Project default (17 - Sealed types, always strict floating-point semantics).
In Modules -> Dependencies I've set the Module SDK to Project SDK openjdk-17.
In Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler I've set the Project bytecode version to 17.

How do I resolve this?
I've a fresh install of netbean 11.1. Now I'm trying to build a project:

I want to get started with Hyperledger Besu, after following the steps of the official documentation here and running the following command:
```shell
bin\besu --help
```

I get the following error:
```
C:\Users\user\Desktop\besu-1.3.9>bin\besu --help
Unrecognized option: --add-opens
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I get the same thing when running bin\besu or bin\besu -help.
```

I don't know if the problem is with java's installation or with hyperledger besu trying to run unvalid/unrecognised option bin\besu --add-opens. I tried uninstalling then reinstalling java but this did not solve the issue, here is java's version:
```

I am trying to run Maven using the Maven wrapper rather than the Maven task. However, it's failing because it is using an older version of Java. The JavaInstaller task seems to require a remote source for the JDK, I would rather avoid doing that and use the one that works with Maven task, but I can't find it documented anywhere.
How to enable Dev Tools project on IntelliJ 2021.2 usinv maven and observe the changes in code without having to restart the Tomcat server?
I am trying to build an application which was built using java 8, now it's upgraded to java 11. I installed Java 11 in my **windows machine** and I use **IntelliJ IDEA 2017** as my IDE.

I changed my system environment variables and set the

```
JAVA_HOME to C:\Program Files\Java\jdk-11.0.1
```

And added that to the `Path` variable.

```
C:\>java -version
java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
```

When I build my application in IntelliJ, this is what I get:

```
Information:java: Errors occurred while compiling module 'test-domain_main'
Information: javac 1.8.0_171 was used to compile java sources
Information:1/10/2019 4:21 PM - Compilation completed with 1 error and 0 warnings in 1s 199ms
Error:java: invalid target release: 11
```

This is what I've tried so far:

1. I changed `.idea/compiler.xml` target values from 8 to 11 but that didn't help. Also, verified the `Target bytecode version` in `settings > Build, Execution, Deployment > Compiler > Java Compiler` and all my modules are set to 11.
2. Went to `file > Project Structure > SDKs *(currently I have 1.7 and 1.7 listed)* > Add new SDK > JDK >` After that, I selected `C:\Program Files\Java\jdk-11.0.1` But it errors out with "The selected directory is not a valid home for JDK"

I am not sure if I installed the wrong JDK 11, because in my `C:\Program Files\Java\`, I see separate JDK and JRE folders for `1.7` and `1.8` but only JDK folder for `11.0.1`

Or is it something else I need to change?
I'm trying to generate a random date and time, and convert it to the `"yyyy-MM-dd'T'HH:mm:ss'Z'"` format.

Here is what I have tried:

```java
  public static String generateRandomDateAndTimeInString() {
    LocalDate date = LocalDate.now().minus(Period.ofDays((new Random().nextInt(365 * 70))));
    System.out.println("date and time :: " + date.toString());
    return formatDate(date) ;
  }

  public static String formatDate(LocalDate date){
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
    return dateFormat.format(date);
  }
```

But in the line `dateFormat.format(date)`, it complains with:

```
java.lang.IllegalArgumentException: Cannot format given Object as a Date
```

The second problem is that, the output of print does not contain the time:

```
date :: 1998-12-24
```

I don't know how to get it to work.
If we want to check the datatype of variable in javascript, we can use `typeof` operator .

Consider this snippet

```javascript
var c = 'str' ;
console.log(typeof(c)); // string
c = 123 ;
console.log(typeof(c)); // number
c =  {} ;
console.log(typeof(c)) ; // object
```

I want to achieve the same functionality in `Java 8` . Java does not have typeof operator but there's the `instanceof` operator to check the types.

```java
System.out.println("str" instanceof String);  // true

Integer a  = 12 ;
System.out.println(a instanceof Integer);


Float f = 12.3f
System.out.println(f instanceof Float); // true
```

Can we do any better ? Plus `instanceof` does not support primitive types .

Is there any approaches in `java 8` ? Any relevant approaches will be appreciated.
I'm trying to add swagger-ui (OpenAPI 3.0) to a Spring Boot v3 application.

I've added the openapi-ui maven dependency, and it should work as per the documentation.

```xml
<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>
    <version>1.6.11</version>
</dependency>
```

But apparently, it still doesn't work and localhost:8080/swagger-ui.html returns an 404 error.

What am I missing?
I'm using C# to develop an ASP.NET project. After upgrading ASP.NET Core 5.0 with IdentityServer4 to 6.0, I got the following error:

```

How to solve this problem using C#?
According with the Microsoft Documentation Here, I should have access to the Attribute for [Keyless] so I can define my Model has Keyless, so that in my DBContext I could have something like:
```c#
public DbSet<MyKeylessClass> KeylessModel { get; set; }
```
And use
```c#
_context.KeylessModel.FromSqlRaw(...)
```
without having the need to add a PK to it. I have the reference to
```c#
System.ComponentModel.DataAnnotations
```
and all the Attributes except Keyless are there, what am I missing here?
I'm facing an issue where the generic implementation of TResponse and TRequest is not enough. For example, I need
```c#
PipelineBehavior<RequestOne, ResponseOne>
```
to do a specific logic for the requestOne, and another
```c#
PipelineBehavior<RequestTwo, ResponseTwo>
```
to do another logic that doesn't apply to request one.
I wonder if having two separate pipelines for two very specific request is a bad practice.
I have an entity user with the following:
public class User { [Key, Required] public int Id { get; set; } public int GenderId { get; set; } public virtual Gender Gender { get; set; } }
In gender:
public class Gender { [Key, Required] public int Id { get; set; } public virtual ICollection<User> Users { get; set; } }
Then, inside my DbContext, I have:
protected override void OnModelCreating(ModelBuilder modelBuilder) { modelBuilder.Entity<User>(user => { user .HasOne(x => x.Gender) .WithMany(x => x.Users) .HasForeignKey(x => x.GenderId); } user.HasIndex(x => x.Gender); }
When I run dotnet ef add migration User, I am getting the error:

I want to inject this interface to my controllers:
```c#
public interface IDatabaseService<T>

But this is a generic interface. When I try to ineject in my Startup.cs, I'll have to pass a generic type like this (which is not feasible):
```c#
services.AddScoped<IDatabaseService<T>>();
```
So what is the correct C# code to inject a generic interface?
I have an entity user with the following:

I want to inject multiple ServiceBusClient with same connectionstring but different queue name.
```c#
    _services.TryAddSingleton(implementationFactory =>
    {
        var serviceBusConfiguration = implementationFactory.GetRequiredService<Microsoft.Extensions.Options.IOptions<UserEventConsumerSetting>>().Value;

        var serviceBusClient = new ServiceBusClient(serviceBusConfiguration.ServiceBusConnectionString, new ServiceBusClientOptions
        {
            TransportType = ServiceBusTransportType.AmqpWebSockets
        });

        return serviceBusClient.CreateReceiver(serviceBusConfiguration.ServiceBusQueueName, new ServiceBusReceiverOptions
        {
            ReceiveMode = ServiceBusReceiveMode.PeekLock
        });
    });
```
In order to use I have to create ServiceBusSender Instance.
```c#
    private readonly ServiceBusSender _serviceBusSender;

    public CarReservationMessagingService(ServiceBusSender serviceBusSender)
    {
        _serviceBusSender = serviceBusSender ?? throw new ArgumentNullException(nameof(serviceBusSender));
    }

    public async Task PublishNewCarReservationMessageAsync(CarReservation carReservation)
    {
        var carReservationIntegrationMessage = new CarReservationIntegrationMessage
        {
            Id = Guid.NewGuid().ToString(),
            CarId = carReservation.CarId,
            CustomerId = carReservation.CustomerId,
            RentFrom = carReservation.RentFrom,
            RentTo = carReservation.RentTo
        };

        var serializedMessage = JsonSerializer.Serialize(carReservationIntegrationMessage);
        ServiceBusMessage message = new ServiceBusMessage(serializedMessage);
        await _serviceBusSender.SendMessageAsync(message);
    }
```
How can I inject multiple servicebusclient and use them differently?
I'm looking for the correct way to return JSON with a HTTP status code in my .NET Core Web API controller. My code is like this:

How to let the WebAPI controller return JSON with a HTTP status code?
How do I create multiple constructors for a record type in C#?
I created a record type like this:
```c#
public record Person(int Id, string FirstName, string LastName)

Now I want to introduce another constructor overload with no parameters, how can I do that?

Specifically, pelase don't add other text and repeat the following paragraph with [blank] filled:

You can write the following code to introduce another constructor overload with no parameters:

I want to store the current date time in MySQL using the following Laravel function. Actually, I stored a static date. Instead of this, how can I store the current date time in the created_at and updated_at fields in the database?

{
    $name = $req->input('name');
    $address = $req->input('address');

    DB::table('student')->insert($data);
    echo "Record inserted successfully.<br/>";
    return redirect('/');
}

I am working on a laravel application. Upon hosting it on my domain, I am running into a "CSRF token mismatch" error. Locally, the application is working fine because I have included the csrf token in the header as shown in the documentation. Therefore, the csrf token is being generated successfully and being included in the header of requests. On doing some debugging, I changed the SESSION_DRIVER in env file to file so that I can see the sessions. I realized that multiple sessions are being generated for one user. The SESSION_LIFETIME is set to 120, which I believe is okay. In looking at the tokens in the sessions stored in storage/framework/sessions, none contains the token that is generated by the browser. What could be the issue? Remember that it is working fine locally. What configurations on the host domain could be affecting the sessions of the application.

how can I increase the laravel 8 dd() limitations? I have lots of nested relationship and I cant view most of them due to many data.
I run the php artisan make:auth command and I will explain step by step what I do after that to understand the scenario,

Login to a new session (example.com/home)
opened a new tab and pasted the URL, ie example.com/home.
Now 2 tabs are open with the same session.
I clicked logout from one of the tabs and it works perfectly fine
Then when I tried to logout from the other tab, it gave me an error saying "419 Page Expired" and it is going nowhere even after reloading.
The thing is, these kinds of scenarios may arise, and I don't want to see this error message, just logout after clicking logout, even if the session is expired.

Note: This issue is not because of not adding @csrf
As my IDE points out, the AbstractController::getDoctrine() method is now deprecated.

I haven't found any reference for this deprecation neither in the official documentation nor in the Github changelog.

What is the new alternative or workaround for this shortcut?

I'm trying to find the best way to create this JSON object using Go:
```json
{
  "Clients" : [
    {
      "Hostname" : "example.com",
      "IP" : "127.0.0.1",
      "MacAddr" : "mactonight"
    },
    {
      "Hostname" : "foo.biz",
      "IP" : "0.0.0.0",
      "MacAddr" : "12:34:56:78"
    }
  ]
}
```
Please write a struct `ClientInfo` in Go, which can be used for serialization. The code context is:
```
package main

import (
	"encoding/json"
	"os"
)

func getASCIIAsString(asciiCode byte) string {
	return string(asciiCode)
}

type ClientInfo struct {
    //You should implement here
}
```
Please give me only the declaration of `ClientInfo` without any other context such as imports.
I'm using go 1.11 with module support. I understand that the go tool now installs dependencies automatically on build/install. I also understand the reason.

I'm using docker to build my binaries. In many other ecosystems it's common to copy over your dependency manifest (package.json, requirements.txt, etc) and install dependencies as a separate stage from build. This takes advantage of docker's layer caching, and makes rebuilds much faster since generally code changes vastly outnumber dependency changes.

I was wondering if vgo has any way to do this?

I developed a repo on computer A and created a go.mod/go.sum that I checked in.

I pull that repo with the go.mod/go.sum files on computer B, but when I try to build the program, the module constraints can't be satisfied.

```bash
$ go build
go: finding github.ibm.com/kms/key-protect-client v0.1.5
go: finding golang.org/x/tools v0.0.0-20180221164845-07fd8470d635
go: github.ibm.com/kms/key-protect-client@v0.1.5: unknown revision v0.1.5
go: error loading module requirements
```
The repo that is failing is a private repo, and for some reason it doesn't get downloaded to the module cache. On another computer, the dependencies are downloaded and the build succeeds. I am building another private repo in that same domain, so I know that my github credentials give me access to these repos. But for some reason, the go module system can't get to the dependent repo.
I cannot find more information how to debug this.
I'm trying to understand the usage of the type union constraint in Go generics (v1.18). Here is the code I tried:
```go
type A struct {
}

type B struct {
}

type AB interface {
    *A | *B
}

func (a *A) some() bool {
    return true
}

func (b *B) some() bool {
    return false
}

func some[T AB](x T) bool {
    return x.some()   // <- error
}
```
The compiler complains:
```
x.some undefined (type T has no field or method some)
```

Getting `error fork/exec /var/task/main: no such file or directory` while executing lambda function.

I am using windows platform to run and build code in Go.

I have done following steps to deploy go aws-lambda handler:

1. Written code in go language with VSCode in windows platform
2. Build project with : go build main.go
3. Convert main.exe to main.zip
4. Uploaded main.zip with handler name main aws-lambda fuction using aws console account
5. Created test event to test lambda function

How do I turn ascii number as string in Go?
Please write a function `getASCIIAsString` in Go, which takes uint64 ASCII code and print the ASCII string of that code.

Function signature is `func getASCIIAsString(asciiCode byte) string `

You only need to output the function implementation itself without any other context.

I am trying to import images to use inside a React component with TypeScript. The bundler I'm using is Parcel (not Webpack).
I have created a `.d.ts` file inside the project with the image file extension, and included it inside `tsconfig.json`. However, when I try to import an image, TS yells at me about `Cannot find module`.
My project structure:
```
+ src
  + assets
    - image.jpg
  + components
    - Box.tsx
    - App.tsx
  - index.d.ts
  - index.html
  - index.tsx
- tsconfig.json
- tslint.json
```typescript
I tried to import the image in App.tsx like this. VS Code underlined '../assets/image.jpg' and said Cannot find module '../assets/image.jpg'.
```
import * as React from 'react';
import * as img from '../assets/image.jpg';

const Box = props => {
  // do things...
}

export default Box;
```
The discussions I found online point to the need of defining a `.d.ts` file myself, so I created that `index.d.ts` file, then added `"include": ["./src/index.d.ts"]` inside `tsconfig.json`.
What did I miss? How can I fix the error TS is throwing?
Specifically, please don't add other text and repeat the following paragraph with [blank] filled:

TypeScript is ignoring `[blank]` because it assumes that it is generated from `index.tsx`, which is more likely to be up to date. Name your `[blank]` file something else, e.g., `declaration.d.ts`.

    } else {
        println!("func 2 returned None");
    }
} else {
    println!("func 1 returned None");

The problem is that the above code is an ugly and unreadable.
Is there really not a better way to do this? I want to refactor the above into something that has a cleaner, flatter structure where everything appears in a sensible order.
What is the idiomatic way to do something when an Option is either None, or the inner value meets some condition?

I am creating a dapp where multiple users can deposit SOL into an event account, and depending on whoever wins the event, they can redeem SOL back to their wallet.

I'm writing a command line application that involves centering text in the terminal. This is the function I wrote to do this:
```rust
use console::{Alignment, pad_str};

fn get_padded_row(row: &str, width: u16, symbol: Option<char>) -> String {
    let symbol = symbol.unwrap_or(' ');
    return pad_str(row, width as usize, Alignment::Center, None)
        .to_string()
        .replace(' ', &symbol.to_string());
}
```
This function works perfectly fine, and there were no errors with it. Then I wrote a test:
```rust
#[cfg(test)]
mod tests {
    use crate::get_padded_row;

    #[test]
    fn row_padding_dashes() {
        let padded_row = get_padded_row("hello", 15, Some('-'));
        assert_eq!(
            padded_row, "-----hello-----".to_string(),
            "`get_padded_row` was not correct, got `{}`", padded_row
        );
    }
}
```
The code still works perfectly fine. Both `cargo run` and `cargo test` work, the function passes the test, and `cargo check` returns no issues. But rust-analyzer gives an error, highlighting everything from the `tr};` in the `use` statement to the `p` right after `return`: "could not resolve macro `$crate::format_args` rust-analyzer(macro-error)". 
What does the error mean and how do I fix it?
How to sort a Vec of structs by 2 or multiple fields?
Example:
```rust

    row: u8,
    column: u8
}

let my_vector = a Vec<MyStruct> with like 100 items in it
```

my_vector = vec![
MyStruct { row: 10, column: 1 },
MyStruct { row: 10, column: 2 },
MyStruct { row: 10, column: 3 }, ]

How to set a field in a struct with an empty value in Rust?
I am writing a TCP client and have a `conn` field in my client struct. My client implements two methods `new` to instantiate the struct and connect to open a connection to the server and set that as the value of the `conn` field.
```rust
pub struct FistClient {
    addr: String,
    conn: TcpStream,
}

impl FistClient {
    pub fn new(ip: &str, port: &str) -> Self {
        FistClient {
            addr: String::from(ip) + ":" + &String::from(port),
            // conn: <some-defaullt-value>,
        }
    }

    pub fn connect(&mut self, ip: &str, port: &str) {
        let res = TcpStream::connect(&self.addr);
        match res {
            Ok(c) => self.conn = c,
            Err(_) => panic!(),
        }
    }
}
```
I want to set the `conn` field in the new method to some default value. How to do it in Rust?
Is there a simple way remove duplicate elements from an array?
I want to remove duplicate elements from an array and I have implement two ways:
```rust
use itertools::Itertools;
use std::collections::HashSet;

#[derive(Debug)]
struct Person {
    name: String,
    age: u32,
}

fn main() {
    let arr = [
        Person { name: "aaa".to_string(), age: 10 },
        Person { name: "bbb".to_string(), age: 20 },
        Person { name: "bbb".to_string(), age: 20 },
        Person { name: "ccc".to_string(), age: 30 },
    ];

    // Way 1:
    let arr2 = {
        let names: Vec<_> = arr.iter().map(|v| v.name.clone()).unique().collect();
        names
            .iter()
            .map(|name| arr.iter().find(|person| &person.name == name).unwrap())
            .collect::<Vec<_>>()
    };
    dbg!(arr2);

    // Way 2:
    let arr2 = {
        let mut names = HashSet::new();
        arr.iter()
            .filter(|p| names.insert(p.name.clone()))
            .collect::<Vec<_>>()
    };
    dbg!(arr2);
}
``` 
Way 2 is simple compared to way 1, but is there anything simpler?
How to get the minimum value within a vector in Rust?

{
    std::string imageDirectory = "./image";;
    std::vector<std::string> imagePath;
    for (const auto& entry: std::filesystem::directory_iterator(imageDirectory))
    {
        imagePath.push_back(entry.path());
        std::cout << entry.path() << std::endl;
    }
    return 0;
}
```
In C++, please complete the following functions:

Have a function named ```my_2d_array(int N, int M)``` which takes two arguments M and N and returns a matrix or 2d-array of dimension (M*N) with elements indicating the position of that element. E.g. calling my_2d_array(4,3) would return:
[[00, 01, 02],
[10, 11, 12],
[20, 21, 22],
[30, 31, 32]]

```c++
#include <vector>
#include <string>
#include <iostream>

std::vector<std::string> my_2d_array(int N, int M) {
    //complete your code here
}

int main() {
    int N, M;
    N = 4;
    M = 3;
    std::vector<std::string> A = my_2d_array(N, M);

    // Print the array A
    for (int i = 0; i < N; i++) {
        for (int j = 0; j < M; j++) {
            std::cout << A[i*M+j] << " ";
        }
        std::cout << "\n";
    }
}
```
Return the implementation of my_2d_array only, without any other information.
Please write a function ```fun``` in C++ that can take multiple parameters of the same type (struct Foo in the following example), passed in as a template. The number of arguments is known in compile time.
There are two constraints: 1. no heap memory allocations. 2. no va_args.
The C++ version is C++14 or new versions.
```c++
struct Foo
{
    int a, b, c;
};

template <uint32_t argsCount, typename T>
void fun(T ...args) // max number of args == argsCount
{
    // ...
    // std::array<T, argsCount>{ args... };
}

int main()
{
    fun<3, Foo>( { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } );
    return 0;
}
```
Replace the function ```fun``` with your implementation.
Complete the function ```vector<pair<int, int>> origin_to_goal(vector<int> origin)```.
The function creat a vector of pairs, where each pair contains always two elements, from a single even-sized vector in C++ without simple loops.
It can be assumed that the original vector always contains an even amount of elements.
Using a nice standard-library tool for this (if you can).
Example:
```c++
vector<int> origin = {1, 2, 3, 4, 5, 6, 7, 8};
vector<pair<int, int>> goal = origin_to_goal(origin); //{ {1, 2}, {3, 4}, {5, 6}, {7, 8} };
```
Return the implementation of origin_to_goal, without any other information.
What is the simplest syntax for string interpolation in c++?
I'm used to easy-to-read syntax for string interpolation like this in c# or JavaScript.
In c# strings are interpolated like this:
```c#
$"My variable has value {myVariable}"
```
In JavaScript it looks like this:
```javascript
`My variable has value ${myVariable}`
```
What is the simplest way of doing this in c++?
Is the Rule of 5 (for constructors and destructors) outdated?
The rule of 5 states that if a class has a user-declared destructor, copy constructor, copy assignment constructor, move constructor, or move assignment constructor, then it must have the other 4.
But today it dawned on me: when do you ever need a user-defined destructor, copy constructor, copy assignment constructor, move constructor, or move assignment constructor?
In my understanding, implicit constructors / destructors work just fine for aggregate data structures. However, classes which manage a resource need user-defined constructors / destructors.
However, can't all resource managing classes be converted into an aggregate data structure using a smart pointer? Am I missing something here?
I am have an issue while overriding the base class operator==.
It complains that:

A constructor cannot be called, it is not a function. It is invoked automatically when a new object is created.

Is the above comment true/correct and why?
How can I distinguish between high- and low-performance cores/threads in C++?
Is there a way to query std::thread‘s properties and enforce on which cores they’ll run in C++?
Please answer "Yes" or "No" first and give the reasons.
In our C++ project, the order of our includes is regularly changed. This is a problem since we are using some third-party libraries which require a specific include order to avoid problems.
Unfortunately, the order of our includes is regularly changed and I suppose that this is due to clang-format.
I simply want to completely disable the ordering of includes. How can I do this?
