Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

public class Javaexcercise{
 
   public static void main(String[] args) {
      String string = "techstudy";
 
      String reverse = new StringBuffer(string).reverse().toString();
      System.out.println("\nString before reverse: "+string);
      System.out.println("String after reverse: "+reverse);
 
   }
}

Result
