Java Booleans

Boolean data type are capable to store true and false value. Generally all comparing and relational operator are produce boolean result. boolean keyword are used to define Boolean data type variables.

public class Result{
  public static void main(String[] args) {
    //Define boolean variables
    boolean isTrue=true;
    boolean isFalse=false;

    //Display boolean variable value
    System.out.println(isTrue);//true
    System.out.println(isFalse);//false
  }
}

true
false

There are many operation which is generate boolean value. That is based on comparison operation.

public class Result{
  public static void main(String[] args) {
    //Basic operation which are produce an boolean value
    System.out.println(true^true); //false
    System.out.println(5>3); //true
    System.out.println(true!=false); //true
    System.out.println(true==false); //false
  }
}

false
true
true
false

Java.lang.Boolean Class

Methods which is publicly used by Boolean wrapper class.

public class Test{
    public static void main(String[] args){
      
      Boolean b1=true,b2=false;

      System.out.println(b1.equals(b2));
      System.out.println(b1.compareTo(b2));
    }
}

false
