Solution Review: Compute an Expression Using Logic

Explore how to compute logical expressions in Java by understanding Boolean operators such as NOT, XOR, and AND. This lesson walks you through evaluating expressions step-by-step, helping you grasp how Boolean logic affects variable values in your code.

We'll cover the following...

Solution: Is it true or false?

Java
class HelloWorld {

    public static void main( String args[] ) {

        boolean x = true;

        boolean y = true;

        boolean answer;



        boolean not_x = !x;

        boolean xor_x = not_x ^ x;

        boolean and_xy = xor_x && y;

        answer = !and_xy;



        System.out.println(answer);

    }

}

Understanding the code

Line 7

  • The variable, not_x stores the result of the Boolean NOT of x.
  • The value of x
