Java Boolean compare() method

The compare() method of Java Boolean class compares the two Boolean values (x and y) and returns an integer value based on the result of this method.

Syntax:

Parameters:

Here, x(first boolean) and y( second boolean) are two boolean parameters passed which are compared.

Return Value:

This method returns an integer value.

It returns value 0, if x==y.
It returns positive value, if x is true and y is false.
It returns a negative value, if x is false and y is true.

Example 1

  public class BooleanCompareExample1 {      public static void main(String[] args) {          Boolean b1 = true;          Boolean b2 = false;          int b3 = Boolean.compare(b1,b2);          if(b3==0){              System.out.println(“Both values are equal”);          }          else if(b3>0){              System.out.println(“b1 value is true”);          }          else{              System.out.println(“b2 value is true”);          }      }  }  

Test it Now

Output:

b1 value is true

Example 2

  import java.util.Scanner;    public class BooleanCompareExample2 {      public static void main(String[] args) {          Scanner scanner = new Scanner(System.in);            int a,b;          System.out.println(“Enter two no.s”);          System.out.print(“I no :”);a = scanner.nextInt();          System.out.print(“II no :”);b = scanner.nextInt();                Boolean b1=(a>b)?true:false;              Boolean b2=(a<b)?true:false;              int val =Boolean.compare(b1,b2);              if(val>0){                  System.out.println(a+” is greater”);                  }                  else if(val==0){                  System.out.println(a+” and “+b+” are equal.”);              }                  else{                  System.out.println(b+” is greater”);              }        }  }  

Output:

Enter two no.s  I no :89  II no :98  98 is greater

Example 3

  import java.util.Scanner;    public class BooleanCompareExample3 {      public static void main(String[] args) {          Scanner scanner=new Scanner(System.in);          System.out.print(“Enter your percentage: “);          Double a = scanner.nextDouble();          boolean b1= true;          boolean b2=false;          if(a>=75){                b2=true;              }              int b3 = Boolean.compare(b1,b2);          if(b3==0){              System.out.println(“Congratulations! you are eligible for the interview”);              }              else{              System.out.println(“Sorry! Your percentage is lower than our requirement. “);          }            }  }  

Output:

Enter your percentage: 74.9999  Sorry! Your percentage is lower than our requirement.
