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);      }  }

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.
