![**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 `](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F319348e8-ec3b-434b-beac-e2801422c409%2F116927d4-fe20-4e49-811d-86873bf952c7%2F0uxbve_processed.png&w=3840&q=75)
