**Java II: First Array**

In this lab, you will be creating your first integer array, populating it, and updating each index using a loop. Type up the code below, execute the program, and submit ONLY the results.

```java
public class ArrayTesting {

    public static void main(String[] args) {
        int[] myIntArr = {2, 4, 6, 8, 10};
        
        for (int x = 0; x < 5; x++) {
            System.out.println("Original value of index " + x + ": " + myIntArr[x]);
            myIntArr[x] += 10;
            System.out.println("The updated value of index " + x + ": " + myIntArr[x]);
        }
    }
}
```

**Explanation:**

- The program defines a class called `ArrayTesting`.
- Inside the `main` method, it initializes an integer array `myIntArr` with the values `{2, 4, 6, 8, 10}`.
- A `for` loop iterates through the array indices from `0` to `4`.
- For each index `x`, it first prints the original value of the current array element.
- It then updates the current array element by adding `10` to its original value.
- Finally, it prints the updated value.

**Purpose:**

This exercise demonstrates how to manipulate array elements using loops in Java. It shows updating array values through arithmetic operations, enabling students to understand basic array handling concepts.

Expert Solution
Step 1

In the given program,

  • First, we create an array named myIntArr of integer type and assign 5 values to it.
  • Then create a for loop and iterate from x=0 to 4.
    • Use x as an index of the array to access each element of the array and display it.
    • Add the value 30 to the array element at index x.
    • Print the updated value of the element at index x.
