Logical Operators Part 2

Part of the Fundamentals section of Coddy's Java journey — lesson 23 of 73.

Logical operators have a special table called "Truth table" that shows what the combination of logical operators returns.

Truth table for the and (&&) operator:

a	b	a && b
false	false	false
false	true	false
true	false	false
true	true	true

The only way to get a true for the and (&&) operator is if both a and b are true

Truth table for the or (||) operator:

a	b	a \|\| b
false	false	false
false	true	true
true	false	true
true	true	true

In this case, to get a true result, either a or b should be true.

Truth table for the not (!) operator:

a	!a
false	true
true	false

Here the value of a is reversed. If a is false then !a is true

Challenge

Beginner

You need to assign integer values to variables b1 and b2 so that b3 evaluates to true in the expression: b3 = !((b1 + b2) > (b1 * b2)).

Cheat sheet

Truth tables show the results of logical operator combinations:

AND operator (&&): Returns true only when both operands are true

a	b	a && b
false	false	false
false	true	false
true	false	false
true	true	true

OR operator (||): Returns true when either operand is true

a	b	a \|\| b
false	false	false
false	true	true
true	false	true
true	true	true

NOT operator (!): Reverses the boolean value

a	!a
false	true
true	false

Try it yourself

public class Main {
    public static void main(String[] args) {
        // Type your code below
        int b1 = ?
        int b2 = ?
        boolean b3 = !((b1 + b2) > (b1 * b2));
        
        // Don\'t change the line below
        System.out.println("b3 = " + b3);
    }
}
