    Default Recursive method that accepts a single string as a parameter and returns the reverse of that String

    write a recursive method that accepts a single String as a parameter and returns the reverse of that String. For example, calling the method reverse("Test would return the String "tesT".

    any suggestion?

    Thanks in advance

    Public String someMethod(String input)
    {
     String output="";
     Char[] reverse=new Char[input.length()];
     reverse=input.tochararray();
    for(int i=input.length();i>=0;i--)
    {
    output+=Character.toString(reverse[i])
    } 
    return output;   
    }

    keep in mind this is a skeleton method and most likely doesn't work due to the fact Im not in front of an IDE to test this out in . i just wanted you to get the idea. Oh this is not recursive btw.(sorry).
