Java.lang.Boolean.toString() Method



The java.lang.Boolean.toString() returns a String object representing this Boolean's value. If this object represents the value true, a string equal to "true" is returned. Otherwise, a string equal to "false" is returned.


Following is the declaration for java.lang.Boolean.toString() method

public String toString()


toString in class Object


  • NA

Return Value

This method returns a string representation of this object.


  • NA


The following example shows the usage of lang.Boolean.toString() method.

package com.tutorialspoint;

import java.lang.*;

public class BooleanDemo {

   public static void main(String[] args) {

      // create 2 Boolean objects b1, b2
      Boolean b1, b2;

      // assign values to b1, b2
      b1 = new Boolean(true);
      b2 = new Boolean(null);

      // create 2 Strings s1, s2
      String s1, s2;

      // assign string value of objects b1, b2 to s1, s2
      s1 = b1.toString();
      s2 = b2.toString();

      String str1 = "String value of boolean object " + b1 + " is "  + s1;
      String str2 = "String value of boolean object " + b2 + " is "  + s2;

      // print s1, s2 values
      System.out.println( str1 );
      System.out.println( str2 );

Let us compile and run the above program, this will produce the following result:

String value of boolean object true is true
String value of boolean object false is false
