Q: If x is 7 and y is 7, what is the result of the expression x >= y using the greater-than-or-equal-to operator in Java?  

If x is 7 and y is 7, the expression x >= y in Java evaluates to true. This is because 7 is equal to 7, and the greater-than-or-equal-to operator (>=) returns true when the left operand is greater than or equal to the right operand.

Here's a simple Java program to illustrate this:

public class GreaterThanOrEqualOperatorExample {
    public static void main(String[] args) {
        // Example values
        int x = 7;
        int y = 7;

        // Check if x is greater than or equal to y
        if (x >= y) {
            System.out.println("x is greater than or equal to y.");
        } else {
            System.out.println("x is not greater than or equal to y.");
        }
    }
}

When you run this program, it will print "x is greater than or equal to y."
