> By the way, even if you are not going to use StringBuffer.reverse(), you should still use a StringBuffer class, not a String. If you keep changing a String, what you are really doing is creating a plethora of slightly different Strings, since each String object is immutable. This is really horribly inefficient code and is the whole reason that StringBuffer exists. So what you should do is start out with an empty StringBuffer and append chars from the String (working backwards, as mentioned), then return StringBuffer.toString().
