Q: If x is false and y is true, what is the result of the expression x && !y using logical AND and logical NOT in Java?  

The logical AND operator (&&) is used to perform a logical AND operation between two boolean expressions. It returns true only if both operands are true. The logical NOT operator (!) negates a boolean expression. In this case, x && !y is false.

If x is false and y is true, the result of the expression x && !y using logical AND (&&) and logical NOT (!) in Java is false.

Here's a breakdown of the expression:

1. x is false.
2. !y is the logical NOT of y, which is !true and evaluates to false.
3. The logical AND (&&) requires both conditions to be true for the entire expression to be true.

Since x is false and !y is also false, the result of the entire expression is false.

Here's an example program:

public class LogicalExample {
    public static void main(String[] args) {
        // Example conditions
        boolean x = false;
        boolean y = true;

        // Using logical AND and NOT operators
        boolean result = x && !y;

        // Displaying the result
        System.out.println("Result of logical AND and NOT: " + result);
    }
}

When you run this Java program, it will output "Result of logical AND and NOT: false".
