Java Boolean equals() method

The equals() method of Java Boolean class returns a Boolean value. It returns true if the argument is not null and is a Boolean object that represents the same Boolean value as this object, else it returns false.

Syntax:

Parameters:

Obj - The object to compare with

Return Value:

This method returns a Boolean value,

It returns true, if the Boolean objects represent the same value.
It returns false, if the Boolean objects represent different value.

Example 1

public class BooleanEqualsExample1 {
    public static void main(String[] args) {
        Boolean b1 = new Boolean(true);
        Boolean b2 = new Boolean(false);
        // method will give the result of equals method on b1,b2 to b3
         if(b1.equals(b2)){
             System.out.println("equals() method returns true");
         }
         else{
             System.out.println("equals() method returns false");
         }
    }
}

Test it Now

Output:

equals() method returns false

Example 2

import java.util.Scanner;

public class BooleanEqualsExample2 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter your percentage.");
        Double d1 = scanner.nextDouble();
        Boolean b1 = true;
        Boolean b2 = false;
        if (d1 > 64) {
            b2 = true;
        if(b1.equals(b2)) {
            System.out.println("Congratulation! you have passed with flying colours.");
             }
        }
        else{
            double d2=64.0-d1;
            System.out.println("Sorry! You have failed. You needed "+d2+" more marks to pass .\nTry again next year.");
        }
    }
}

Output:

Enter your percentage.
60
Sorry! You have failed. You needed 4.0 more marks to pass.
Try again next year.

Example 3

import java.util.Scanner;

public class BooleanEqualsExample3 {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter two number.");
        int a[] = new int[3];
        for (int i = 0; i < 2; i++) {
            a[i] = scanner.nextInt(); 
        }
        Boolean b1 = true;
        Boolean b2 = false;
        int val=0;
        int rem=0;
        for (int i = 0; i < 2; i++) {
            if (a[1] == 0) {
                b2 = true;

                break;
            }
            else{
                val = a[i]/a[i+1];
                rem= a[i]%a[i+1];
                break;
            }
        }
        if (b1.equals(b2)) {
            System.out.println("Divide = "+a[0]+"/"+a[1]+"\nDivision  is not possible.");
        } else {
            System.out.println("Divide = "+a[0]+"/"+a[1]+"\nAfter division.\nQuotient = "+val +"\nRemainder = "+rem);
            }
    }
}

Output:

Enter two number.
78
0
Divide = 78/0
Division  is not possible.
