The following example shows the usage of java.lang.String.valueOf() method.

package com.tutorialspoint;

import java.lang.*;

public class StringDemo {

   public static void main(String[] args) {

      String str = "compile online";
      Object objVal = str;
   
      // returns the string representation of the Object argument
      System.out.println("Value = " + str.valueOf(objVal));
