Java.lang.Boolean.toString() Method

Description

The java.lang.Boolean.toString(boolean b) returns a String object representing the specified boolean. If the specified boolean is true, then the string "true" will be returned, otherwise the string "false" will be returned.

Declaration

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

public static String toString(boolean b)

Parameters

• b - the boolean to be converted

Return Value

This method returns the string representation of the specified boolean.

Exception

• NA

Example

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 primitives bool1, bool2
      boolean bool1, bool2;

      // assign values to bool1, bool2
      bool1 = true;
      bool2 = false;

      // create 2 String's s1, s2
      String s1, s2;

      /**
       *  static method is called using class name 
       *  assign string value of primitives bool1, bool2 to s1, s2
       */
      s1 = Boolean.toString(bool1);
      s2 = Boolean.toString(bool2);

      String str1 = "String value of boolean primitive " +bool1+ " is "  +s1;
      String str2 = "String value of boolean primitive " +bool2+ " 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 primitive true is true
String value of boolean primitive false is false
