Boolean (Part 9)

Java Boolean

Very often, in programming, you will need a data type that can only have one of two values, like:

  • YES / NO
  • ON / OFF
  • TRUE / FALSE

For this, Java has a boolean data type, which can take the values true or false.

A boolean type is declared with the boolean keyword and can only take the values true or false:


Eg:-
 public class MyClass {    
   public static void main(String[] args) {    
   boolean b1=true;    
   boolean b2=false;    
   boolean b3=(b1==b2);    
   System.out.println(b1);    
   System.out.println(b2);    
   System.out.println(b3);    
   }      
  }
Output:-
 true  
 false  
 false

There are many operators that you can implement while using boolean .
