Q: What is the value of z after the expression z %= 6 is executed in Java?  

The compound assignment operator (%=) in Java is used to calculate the remainder of the division of the left operand by the right operand and assign the result to the left operand. In this case, z %= 6 is equivalent to z = z % 6.

public class ModulusAssignmentExample {
    public static void main(String[] args) {
        // Define the value of z
        int z = 17;

        // Perform modulus assignment (z %= 6)
        z %= 6;

        // Display the updated value of z
        System.out.println("Updated value of z after z %= 6: " + z);
    }
}

When you run this program, it will output:

Updated value of z after z %= 6: 5

This is because the modulus assignment operator %= calculates the remainder when the left operand is divided by the right operand and assigns the result to the left operand. In this case, 17 % 6 results in a remainder of 5, so z is updated to 5.
