It means you have tried to access a character in a string where the index given is outside the string, e.g. you have a string "hello" and try to index charAt(10).
http://java.sun.com/j2se/1.4.2/docs/...Exception.html

The error is in line 70 of your code !

If you can't fix the problem from horace's help, you should probably provide the context in which you are calling the Sort function (i.e. the lines where you actually call it) and the relevant section in Sort.
