Answer: A

Explanation:

The compound assignment operator (+=) in Java is used to add the right operand to the left operand and assign the result to the left operand. In this case, x += 5 is equivalent to x = x + 5.


public class PlusEqualsExample {
    public static void main(String[] args) {
        // Define the initial value of x
        int x = 10;

        // Use the += operator to add 5 to x
        x += 5;

        // Display the updated value of x
        System.out.println("Value of x after x += 5: " + x);
    }
}

When you run this program, it will output:


Value of x after x += 5: 15
