Q: If p is false and q is false, what is the result of the expression !(p && q) using logical NOT in Java?  

The logical AND operator (&&) is used to perform a logical AND operation between two boolean expressions. It returns true if both expressions are true and false otherwise.

If p is false and q is false, the expression !(p && q) using logical NOT (!) will evaluate to true. This is because the inner expression (p && q) evaluates to false, and negating false with ! results in true. Here's an example program:

public class LogicalNotExample {
    public static void main(String[] args) {
        // Example boolean values
        boolean p = false;
        boolean q = false;

        // Using logical NOT operator
        boolean result = !(p && q);

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

In this example, the logical NOT operation will result in true. Feel free to run this Java program to see the output.
