Java Boolean booleanValue() method

The booleanValue() method of Java Boolean class returns the primitive Boolean value of this Boolean object.

Syntax:

Parameters:

Return Value:

This method returns the primitive Boolean value of this Boolean object.

Example 1

public class BooleanBooleanValueExample1 { 
    public static void main(String[] args) {
        // here we have created boolean object b
        Boolean b1 = new Boolean(true);
        boolean b2;
        //assigning boolean value of b1 to b2
        b2= b1.booleanValue();
        String str1 = "1. Value of boolean object "+b1+" is "+b2+".";
        System.out.println(str1);
        System.out.println();
        Boolean b3 = new Boolean(true);
        //assigning boolean value of b3 to b4
        boolean b4 = b3.booleanValue();
        String str2 = "2. Value of boolean object "+b1+" is "+b2+".";
        System.out.println(str2);

          }
}

Test it Now

Output:

1. Value of boolean object true is true.

2. Value of boolean object true is true.

Example 2

import java.util.Scanner;

public class BooleanBooleanValueExample2 {
    public static void main(String[] args) {
        Boolean stop = true;
        Scanner scanner=new Scanner(System.in);
        System.out.print("Elements are: ");
        for(int i=0;i<10;i++) {
            System.out.print(i+" ");
            if (i==5) {
                stop = false;
                break;
            }
        }
        System.out.println();
        System.out.println("Stop value is "+stop.booleanValue());
    }
}

Output:

Elements are: 0 1 2 3 4 5 
Stop value is false

Example 3

import java.util.Scanner;

public class BooleanBooleanValueExample3 {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.println("Enter two number");
        System.out.print("I no:"); int a=scanner.nextInt();
        System.out.print("II no:"); int b=scanner.nextInt();

        Boolean b3=(a>b)?true:false;
        if(b3.booleanValue()){
            System.out.println(a+" is greater.");
        }
        else{
            System.out.println(b+" is greater.");
        }
    }
}

Output:

Enter two number
I no:89
II no:90
90 is greater.

Example 4

public class BooleanBooleanValueExample4 {
    public static void main(String[] args) {
        boolean b1 = true;
        Boolean b2 = b1.booleanValue;
        System.out.println("Value is "+b2);
    }
}

Test it Now

Output:

Error:(4, 24) java: boolean cannot be dereferenced

The Boolean is a primitive data type. Its object can't be used to call the Boolean class method. If done, so it will give the above error.
