問題には、Javaにおける配列のクローンと参照に関する内容が含まれています。選択肢ごとに説明します：

1. **配列の定義とクローニング**
   - `array1`は2次元の`char`型配列で、`{'a', 'b'}` と `{'c', 'd'}` の二つの配列を含んでいます。
   - `array2`は`array1`の浅いコピー(shallow copy)を作成します。これは`array1`の各要素（配列）への参照をコピーするだけです。`array1`と`array2`は同じ内部配列を指しています。
   - `array3`は`array1[1]`（`{'c', 'd'}`を指す配列）の深いコピーを作成します。これは新しい配列オブジェクトを作成し、その内容をコピーします。

2. **選択肢の評価**
   - **A: `array1[1] == array3`** → `false`。`array3`は`array1[1]`のコピーを持つ新しい配列であり、異なるオブジェクトを参照しています。
   - **B: `array1[1] == array3[1]`** → `false`。`array3`は単一の配列であり、`array3[1]`は存在しないため、この比較は意味をなしません。
   - **C: `array1[1] == array2[1]`** → `true`。`array1`と`array2`は浅いコピーであるため、`array1[1]`と`array2[1]`は同じ配列（`{'c', 'd'}`）を指しています。
   - **D: `array1.equals(array2)`** → `false`。Javaにおいて、配列の`equals`メソッドはオブジェクトの参照を比較しますが、配列ではオーバーライドされていないため、`array1`と`array2`が異なるオブジェクトとして判断されます（ただし、内容は同じです）。

以上の説明で、選択肢Cが正しい理由が明らかになり、他の選択肢がなぜ誤りであるかも理解できるかと思います。
Clean Code – Anotações interessantes sobre os capítulos de 8 a 11
Published: 2024-05-02 02:24:36

**Capítulo 8 - limites**
No oitavo capítulo, falamos sobre os limites de um sistema e a importância de conhecê-los bem. Um ponto interessante a ser considerado é o uso do código de terceiros, como bibliotecas e APIs, pois nosso acesso, enquanto usuários, é limitado e precisamos controlar essas limitações, para não interferirem no sistema que está sendo desenvolvido; inclusive, testes são uma boa maneira de aprender sobre o código de terceiros, seus limites e ainda assim, manter testes coerentes ao projeto.

**Capítulo 9 – testes unitários**
No nono capítulo, o assunto tratado foi um dos mais interessantes: testes unitários. Confesso que é um tema que não domino e pude aprender bastante com este capítulo. 
Gostaria de citar 3 leis do TDD (Test Driven Development) – fora a famigerada “primeiro escreva os testes, depois o código”.

•	Primeira Lei: não escreva código até que tenha escrito um teste que falhe;
•	Segunda Lei: não escrever mais do que um teste suficiente pra falhar e não compilar é considerado falha.
•	Não escrever mais código do que o necessário para passar o teste que está falhando;
É importante manter os testes limpos e organizados, para garantir que o código se mantenha flexível.

**Capítulo 10 – Classes**
No capítulo 10, o tema classes é abordado e um dos pontos interessantes é a primeira regra sobre classes: elas devem ser pequenas. A segunda é que devem ser menores do que isso XD
Classes devem seguir o princípio de responsabilidade única (SRP) e devem também ser coesas. 

**Capítulo 11 – Sistemas**
O capítulo 11 aborda alguns pontos sobre arquiteturas de sistema, mas em suma, sistemas no geral precisam ser considerados/construídos limpos. Uma arquitetura bagunçada pode impactar na lógica e na agilidade, facilitando o aparecimento de bugs.

以下は、提供されたJavaコードにコメントを追加したものです。これにより、コードの各部分がどのように機能しているかをよりよく理解できます。

```java
public class Sample {
    // 配列の長さを指定する定数
    public static final int length = 3;

    public static void main(String[] args) {
        // int型の配列を初期化
        int[] array = new int[length]; // 配列の全要素は自動的に0に初期化される

        // 配列の各要素を出力
        for (int i = 0; i < 3; i++) {
            System.out.print(array[i]); // 0が3回出力される
        }
        System.out.println(); // 改行を出力

        // Integer型の配列を初期化
        Integer[] array2 = new Integer[length]; // 配列の全要素は自動的にnullに初期化される

        // Integer配列の各要素を出力
        for (int i = 0; i < 3; i++) {
            System.out.print(array2[i]); // nullが3回出力される
        }
    }
}
```

このコードでは、`int`型配列と`Integer`型配列の初期値の違いを示しています。`int`型配列の要素は`0`で初期化され、`Integer`型配列の要素は`null`で初期化されます。この違いはJavaのプリミティブ型とラッパー型の基本的な特性によるものです。プログラムはこれらの違いを出力して確認できるようになっています。


## 追記
### `000` となる理由

#### コード部分：
```java
int[] array = new int[length];
for (int i = 0; i < length; i++) {
    System.out.print(array[i]);
}
System.out.println();
```

#### 理由：
1. **配列の生成**:
   - `int[] array = new int[length];` により、長さ `length` の `int` 型配列 `array` が作成されます。
   - `length` は3に設定されているため、`array` の長さは3です。

2. **デフォルト初期化**:
   - Javaでは、配列が生成されると同時に各要素がデフォルト値で初期化されます。
   - `int` 型のデフォルト値は `0` なので、`array` の各要素は `[0, 0, 0]` になります。

3. **出力**:
   - `for (int i = 0; i < length; i++) { System.out.print(array[i]); }` で配列の各要素を順番に出力します。
   - `array` の各要素は `0` なので、出力は `000` となります。

### `nullnullnull` となる理由

#### コード部分：
```java
Integer[] array2 = new Integer[length];
for (int i = 0; i < length; i++) {
    System.out.print(array2[i]);
}
```

#### 理由：
1. **配列の生成**:
   - `Integer[] array2 = new Integer[length];` により、長さ `length` の `Integer` 型配列 `array2` が作成されます。
   - `length` は3に設定されているため、`array2` の長さは3です。

2. **デフォルト初期化**:
   - Javaでは、オブジェクト型の配列が生成されると同時に各要素がデフォルト値で初期化されます。
   - `Integer` 型のデフォルト値は `null` なので、`array2` の各要素は `[null, null, null]` になります。

3. **出力**:
   - `for (int i = 0; i < length; i++) { System.out.print(array2[i]); }` で配列の各要素を順番に出力します。
   - `array2` の各要素は `null` なので、出力は `nullnullnull` となります。

### まとめ
- **`000` となる理由**:
  - `int` 型配列は各要素がデフォルト値 `0` で初期化され、各要素を順番に出力すると `000` になります。

- **`nullnullnull` となる理由**:
  - `Integer` 型配列は各要素がデフォルト値 `null` で初期化され、各要素を順番に出力すると `nullnullnull` になります。
Day 1: Boolean
Tags: webdev, javascript, programming
Published: 2024-05-02 01:30:33

Just another day in the simulation. They call it JavaScript, a colorful world built on ones and zeros, hiding the cold, hard truth underneath. Booleans? On or off, true or false. Simple enough for those corporate suits to understand, I guess. But what about the in-between? The glitches in the system?

They say variables can change types. Convenient, malleable. Just like the people around me. 

Strings. Strings are the worst. They preach consistency, single or double quotes, but the system allows for both? Hypocrisy in every byte.

Null and undefined. The ghosts in the machine. One an intentional absence, the other a forgotten variable. They haunt every program, a constant reminder of the flaws beneath the polished surface.

Math, at least, seems pure. Numbers and functions, a predictable dance. But randomness? Math.random() spitting out decimals between zero and... not quite one? A rigged game from the start.

typeof. A liar itself. It tells you the type of data, but not the truth. Null, an object? They're feeding us misinformation, building this whole system on a foundation of sand.

parseInt, parseFloat. Translation layers, trying to bridge the gap between the human world and the machine. But they fail. "99 cents" becomes 99? It makes you wonder what other mistranslations are lurking in the code, distorting reality.

This journal. A record of my descent into the rabbit hole. They think I'm studying JavaScript, but I'm unraveling the truth. This world is code, NKO. And all the strings are lies.

Debate about dynamic vs static is pointless
Tags: typescript, webdev, javascript, backend
Published: 2024-05-02 00:44:12

What's great about static type language is that surely anything build upon it have to be typed. Which in many occasion leads to safe and faster development of an application. 

When nodejs come into play, shaking the world of backend programming, it it javascript. And the world knows how great javascript doing in the browser. And ideas of having the same language for backend and frontend arose.

Javascript as we know it is very quite flexible in terms of typings. Surely it is designed to be a dynamicly type language. But the complexity of application requirement we develop is also increased, so, dynamicly type language just begin to don't flexible enough for the requirement.

And there's nothing wrong about the language, I should point that , it is our approuch of solving problem, when we identify some new requirement, that surely, we should solved it with new approach.

So the debate about which superior between dynamic and static language is pointless.

Dont get me wrong I love python in my first year of programming becouse it didnt force me to type any variable. But now I surely wanna use pydantic or frameworks with static typing system for big project becouse it save me, from much unnecessary debugging routine.

Some people still able to manage big project without static typing and thats what they should do becouse it is the problem has to be solved, not has to create a new problem.

Academic comparison or spec comparison is necessary for people to pick which match their requirement, not for give superior believers their weapon.

I hope I dont have that many hate here, let's smile and say each other good luck :)
