What is the state of the array after executing the following code? int[][] a = new int[5][5]; for (int i = 0; i < a.length; i++) { a[i][i] = i * 2; } int loc = 0; %3D for (int i = a.length - 1; i > 0; i--) { a[loc][i] = i * 2; loc++; } loc = 2; %3D for (int i = 0; i < a.length; i++) { %3D a[i][loc] = i * 2; } for (int i = 0; i < a.length; i++) { a[loc][i] = i * 2; %3D }

**Analyzing the Final State of a 2D Array in Java**

This guide examines the final state of a two-dimensional integer array after executing a sequence of Java loops.

### Initial Array Declaration:
```java
int[][] a = new int[5][5];
```
- Initializes a 5x5 integer array `a` filled with zeros.

### First For Loop:
```java
for (int i = 0; i < a.length; i++) {
    a[i][i] = i * 2;
}
```
- **Description:** Iterates through the array diagonally, assigning values.
- **Effect:** Sets the diagonal values to `0, 2, 4, 6, 8`, based on the multiplication of the index `i` by 2.
- **Result:**
  ```
  [0, 0, 0, 0, 0]
  [0, 2, 0, 0, 0]
  [0, 0, 4, 0, 0]
  [0, 0, 0, 6, 0]
  [0, 0, 0, 0, 8]
  ```

### Second For Loop:
```java
int loc = 0;
for (int i = a.length - 1; i > 0; i--) {
    a[loc][i] = i * 2;
    loc++;
}
```
- **Description:** Modifies values in the first row from right to left.
- **Effect:** Sets values in the first column from `8` down to `2`.
- **Result:**
  ```
  [0, 0, 0, 0, 8]
  [0, 0, 0, 6, 0]
  [0, 0, 4, 0, 0]
  [0, 2, 0, 0, 0]
  [0, 0, 0, 0, 8]
  ```

### Third For Loop:
```java
loc = 2;
for (int i = 0; i < a.length; i++) {
    a[i][loc] = i * 2;
}
```
- **Description:** Modifies the third column by iterating through each row.
- **Effect:** Sets column values from `
