**Understanding Data Types in Java
**Java a flexible and popular programming language, greatly depends on the idea of [data types in java](https://www.javatpoint.com/java-data-types)  for efficient information management and manipulation. Java is a statically-typed language because data types specify the kind of data that a variable can contain. This ensures tight type-checking at compile time by requiring a variable's type to be stated before it is used.
Primitive Data Types:
For the purpose of representing basic values like integers, characters, floating-point numbers, and booleans, Java offers a collection of primitive data types. The foundation for more intricate data structures is made up of these basic data kinds. The primary primitive [data types in Java](https://www.javatpoint.com/java-data-types) are as follows:
int:
The int data type is used to represent integer values. It has a width of 32 bits, allowing it to store values ranging from -2^31 to 2^31 - 1.
int myNumber = 42;
Double:
The double data type in java is used for floating-point numbers. It has a width of 64 bits and is commonly used for representing decimal values.
double myDecimal = 3.14;
char:
The char data type represents a single character and is enclosed in single quotes.
char myChar = 'A';
boolean:
The boolean data type has only two possible values: true or false. It is commonly used for logical operations and decision-making.
boolean isJavaFun = true;
Reference Data Types:
Java allows reference data types, which are used to refer to objects, in addition to primitive data types. These objects may be arrays or instances of classes. Reference data types store a reference to the memory location where the data is stored rather than the actual data. Here are a few reference data types that are frequently used:
String:
 String is a reference data type, despite the fact that it is frequently used as a primitive type. In Java, strings are String class instances.
String myString = "Hello, Java!";
Array:
Arrays are used to store multiple values of the same data type. They can be of any primitive or reference type.
int[] numbers = {1, 2, 3, 4, 5};
Class and Object:
User-defined data types are created using classes. Instances of these classes are objects, and they can have attributes (fields) and behaviors (methods).
class Dog {
    String name;
    int age;
}

Dog myDog = new Dog();
myDog.name = "Buddy";
myDog.age = 3;
Java allows for both explicit and implicit type casting. There is no chance of data loss when a smaller data type is assigned to a larger data type; implicit casting occurs automatically. Conversely, explicit casting necessitates that the programmer explicitly convert data between different types, which frequently results in data loss.
int smallNumber = 10;
double largerNumber = smallNumber; // Implicit casting

double anotherNumber = 3.14;
int truncatedNumber = (int) anotherNumber; // Explicit casting

Techniques and Strategies to increase Graph Performance
Published: 2023-11-20 05:33:19

**Introduction**
Apache Age, a graph database leveraging PostgreSQL, offers powerful functionalities for managing interconnected data. This article focuses on optimization techniques to enhance performance in Apache Age, including indexing strategies, query optimization, and data modeling approaches.

**1. Indexing Strategies:**
One of the fundamental ways to enhance Apache Age's performance is through indexing. Indexes act as roadmaps to data, allowing the database to quickly locate specific information. Apache Age offers various indexing options to cater to different query needs. By strategically creating indexes on frequently accessed columns or properties, you can significantly speed up query execution.
Example for creating an index in Apache Age:

5 Common CSS Mistakes: Exploring Best Practices | Part 2
Tags: css, webdev, ui, design
Published: 2023-11-20 05:32:18

In [Part 1](https://dev.to/rohitsondigala/5-common-css-mistakes-what-to-avoid-for-clean-efficient-code-part-1-ej5), we explored five common CSS mistakes that can lead to messy, inefficient, or buggy code. Now, let's delve into additional pitfalls to avoid and refine your CSS practices for cleaner, more maintainable development.

**Part 1:** [Read Now](https://dev.to/rohitsondigala/5-common-css-mistakes-what-to-avoid-for-clean-efficient-code-part-1-ej5)

### 6. Overcomplicating Selectors

❌ Bad:
```CSS
.blog-post .entry-title h1 {
  font-size: 24px;
  margin-bottom: 10px;
}
```
✔ Good:
```CSS
.entry-title h1 {
  font-size: 24px;
  margin-bottom: 10px;
}
```
Using long, overly specific selectors can make your CSS code difficult to read and maintain. Instead, try to use more general selectors that can be reused throughout your code.

### 7. Neglecting CSS Specificity
❌ Bad:
```CSS
.button {
  color: red;
}

.button.warning {
  color: yellow;
}
```
✔ Good:
```CSS
.button {
  color: red;
}

.button.warning {
  color: yellow;
  background-color: #f8f9fa;
}
```

CSS specificity determines which rule should be applied when multiple rules conflict. Understanding CSS specificity can help you avoid unintended overrides and ensure that your styles are applied correctly.

### 8. Ignoring Naming Conventions
❌ Bad:
```CSS
.btn-red {
  background-color: red;
}

.btn-green {
  background-color: green;
}
```
✔ Good:
```css
.primary-button {
  background-color: red;
}

.secondary-button {
  background-color: green;
}
```

Consistent naming conventions make your CSS code more readable and easier to understand. Use descriptive names that clearly indicate the purpose of each class or ID.

### 9. Overlooking Code Optimization
❌ Bad:
```css
body {
  font-family: Arial, sans-serif;
}

body p {
  font-family: Arial, sans-serif;
}
```
✔ Good:
```css
body, p {
  font-family: Arial, sans-serif;
}
```

Combining similar selectors can reduce the amount of code you need to write, making your CSS more concise and efficient.

### 10. Forgetting to Comment
❌ Bad:
```css
/* No comments */
.button {
  color: red;
}
```

✔ Good:
```css
/* This class defines the styling for buttons */
.button {
  color: red;
}
```

Comments are essential for explaining the purpose of your code, especially in complex or non-obvious situations. Well-placed comments can significantly improve code readability and maintainability.

By avoiding these common mistakes and adopting better CSS practices, you can write cleaner, more maintainable code that is easier to understand and modify in the future. Remember, good CSS is not just about making your website look great; it's also about writing code that is efficient, scalable, and easy to work with.

Tags: javascript, typescript, programming, development
Published: 2023-11-20 05:30:24

I have eslint rule to fix any import with type inside curly braces i.e 
import { type Rule } from 'module'; 
as 
import type { Rule } from 'module'; 

when i run test case it doesn't even reach my eslint-rule and even fails initially saying "A fatal parsing error occurred: Parsing error: Unexpected token Rule" and 
iam using "parser": "@typescript-eslint/parser" and  
const ruleTester = new RuleTester({ parserOptions: { ecmaVersion: 2021, sourceType: 'module' } }); in test cases.

Selenium
Published: 2023-11-20 04:44:13

## **1. <u>What is selenium?</u>**

Selenium is a free open source automation testing framework used to validate web application across different browsers and platform. It supports many programming language like Python, Javascript, etc,.

- Selenium automates web applications only.
- Selenium does not automates desktop applications.
- Selenium came with Java support first. Later, it started to support Python, PHP, Javascript, C#, Ruby etc.
- Testing using the selenium framework is called selenium testing.

**Selenium test tool suite:**

- Selenium IDE.
     Selenium IDE (Integrated Development Environment) is primarily a record/run tool that a test case developer uses to develop Selenium Test cases. Selenium IDE is an easy-to-use tool from the Selenium Test Suite and can even be used by someone new to developing automated test cases for their web applications.


- Selenium Webdriver.
     Selenium WebDriver is a collection of open source APIs which are used to automate the testing of a web application. Description: Selenium WebDriver tool is used to automate web application testing to verify that it works as expected. It supports many browsers such as Firefox, Chrome, IE, and Safari.


- Selenium Remote Control.
     Selenium RC is an important component in the Selenium test suite. It is a testing framework that enables a QA or a developer to write test cases in any programming language in order to automate UI tests for web applications against any HTTP website.


- Selenium Grid.
     Selenium Grid is a smart proxy server that makes it easy to run tests in parallel on multiple machines. This is done by routing commands to remote web browser instances, where one server acts as the hub. This hub routes test commands that are in JSON format to multiple registered Grid nodes.


## **2. <u>Why do we use Selenium for automation?</u>**

Selenium automates web browser. Primarily it is used for automating web application for testing purposes, but it is certainly not limited to just that. Different browsers like Chrome, Mozilla Firefox, Safari and Internet Explorer are supported by it, and you can easily automate browser testing across these browsers using the benefits of Selenium. Boring web based administration tasks can also be automated as well. You can also see automated tests being performed on your computer screen.
