Reverse a string in java

Here in this section I'll put solution of some simple programming problem which. The following one will reverse a string.

import java.util.Scanner;

public class MyStack {

 
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  Scanner scanner = new Scanner(System.in);
  String string = scanner.nextLine();
  String output = "";
  StringBuilder stringBuilder = new StringBuilder();
  
  output = stringBuilder.append(string).reverse().toString();
  System.out.println(output);  
  
 }

}
