Java Boolean logicalXor() Method

The logicalXor() method of Java Boolean class returns the result of implementing logical XOR operation on the specified Boolean operands.

Syntax:

public static boolean logicalXor (boolean a, boolean b)

Parameters:

The parameters ‘a’ and ‘b’ represents first and second operands.

Return Value:

The logicalXor () method returns the result after implementing logical AND operation on the parameters ‘a’ and ‘b’.

• It returns true, if the parameters ‘a’ and ‘b’ are different.
• It returns false, if both the parameters are identical.

Example 1:

public class JavaBooleanLogicalXorMethodExample1 {
    public static void main(String[] args) {
        Boolean b1 = true;
        Boolean b2 = false;
        // return boolean value after implementing logical XOR operator
        Boolean b3 = Boolean.logicalXor(b1,b2);
        Boolean b4 = Boolean.logicalXor(b1,b1);
        Boolean b5 = Boolean.logicalXor(b2,b2);
        Boolean b6 = Boolean.logicalXor(b2,b1);
        System.out.println("1. "+b1+"  "+b2+" = "+b3);
        System.out.println("2. "+b1+"  "+b1+" = "+b4);
        System.out.println("3. "+b2+"  "+b2+" = "+b5);
        System.out.println("4. "+b2+"  "+b1+" = "+b6);
    }
}

Output:

1. true false = true
2. true true = false
3. false false = false
4. false true = true

Example 2:

public class JavaBooleanLogicalXorMethodExample2 {
    public static void main(String[] args) {
        //it will return an exception if we pass a null value
        Boolean b1 = null;
        Boolean b2 = false;
        boolean b3 = Boolean.logicalOr(b1,b2);
        System.out.println(b3);
    }
}

Output:

Exception in thread "main" java.lang.NullPointerException

Example 3:

import java.util.Scanner;
public class Boolean_logicalXorMethodExample3 {
    public static void main(String[] args) {
        Scanner scanner =new Scanner(System.in);
        System.out.println("Q How many hours are there in a day?");
        System.out.print("Ans: "); int a = scanner.nextInt();
        Boolean b1 = false;
        Boolean b2 = false;
        if(a==24){
            b1 = true;
        }
        Boolean bool = Boolean.logicalXor(b1,b2);
        if(bool == true){
            System.out.println("Answer is right.");
        }
        else{
            System.out.println("Answer is wrong.");
        }
    }
}

Output:

Q How many hours are there in a day?
Ans: 24
Answer is right.
