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.
