Boolean data type and its exmples in java programming


  • Boolean is a primitive data type.
  • Boolean is the smallest data type in Java which is made up of only 1 bit.
  • Boolean data type represents only two possible values -  True and False.
  • The default Boolean value is False.

Syntax to Declare Boolean variable :

 boolean <variable name> = <default value>;

Example:

  boolean x = true;
  boolean y = false;

Simple Sample Program Describing Boolean Data Type:

  public class Main {
    public static void main(String[] args) {
      boolean x = true;    
      System.out.println("x is " + x);

      int y = 5;
      boolean z = (y > 15);
      System.out.println("z is " + z);
      }
    } 

Output:

  x is true
  z is false
