Boolean class booleanValue() method

  • booleanValue() method is available in java.lang package.
  • booleanValue() method is used to return the value denoted by this Boolean object converted to type boolean (by casting).
  • booleanValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • booleanValue() method does not throw an exception at the time of conversion from Boolean to boolean.


    public boolean booleanValue();


  • It does not accept any parameter.

Return value:

The return type of this method is boolean - it returns a converted (from type Boolean to boolean) value represented by this Boolean object.


// Java program to demonstrate the example 
// of booleanValue() method of Boolean class

public class BooleanValueOfBooleanClass {
    public static void main(String[] args) {
        // It returns boolean value denoted by this Boolean ob1 object
        // and converted to a boolean by calling ob1.booleanValue()
        Boolean ob1 = new Boolean(true);

        // Display ob1 result
        System.out.println("ob1.booleanValue(): " + ob1.booleanValue());

        // It returns boolean value denoted by this Boolean ob2 object
        // and converted to an boolean by calling ob2.booleanValue()
        Boolean ob2 = new Boolean(false);

        // Display ob2 result
        System.out.println("ob2.booleanValue(): " + ob2.booleanValue());


ob1.booleanValue(): true
ob2.booleanValue(): false
