Java - Reverse String using recursion

This is a method I wrote using recursion to reverse a string. Recursions really not the best solution for anything, but this one turned out pretty cool.

Code:

---

public class ReverseString
{
 public String reverse(String arg)
 {
        String tmp = null;
        if (arg.length() == 1)
        {
                return arg;
        }
       
        else
        {
       
                String lastChar = arg.substring(arg.length()-1,arg.length());
               
                String remainingString = arg.substring(0, arg.length() -1);

                tmp = lastChar + reverse(remainingString);
                return tmp;
               
               
        }
  }
}

---

Code:

---

import java.io.*;


public class TestReverse
{
        public static void main(String[] args) throws IOException
        {
                System.out.println("Enter a line to be reversed");
                BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
                String inData;
                inData = br.readLine();
                ReverseString rs = new ReverseString();
                System.out.println("Reversed: " + rs.reverse(inData));       
        }
}

Nice, but probably more efficient this way...

Code:

---

private static String reverseString(String s)
{
  return (new StringBuffer(s)).reverse().toString();
}

Yes, but that isn't much fun.

Just did this one. Enter text and recursion method will reverse it.

Code:

---


import java.util.Scanner;

public class recursionDemo{

        public static void main (String[] args){
       
                Scanner scan = new Scanner (System.in);
               
                System.out.println("Enter text to reverse: ");
                String s = scan.nextLine();
                reverse(s);
               
        }
               
        public static void reverse(String s){
       
                if (s.length() == 1){
                        System.out.print(s);
                }
                else{
                       
                        reverse (s.substring(1, s.length())); 
                        System.out.print(s.substring(0,1));

                }
        }
       
}
