StringList character rotation

[aquafoam]

Please please help! I would appreciate it so much :) Sorry if I am posting in the wrong place, I just started... :)

I'm trying to get a StringList of all the rotations for a given string, such as abcd

ie. abcd -> bcda -> cdab -> dabc

but I only seem to be able to get one with my code

public static String iterations(String s) {
StringBuffer iteration = new StringBuffer(butFirst(s));
iteration.append(first(s));
return iteration.toString();
}

the two methods

first(s) gives the first letter of the string, ie. a of abcd
butFirst(s) gives the rest of the string, ie. bcd of abcd

could someone please help me get a list of all the rotations? I tried using a for loop but it doesn't seem to work...

Don't cross post.

This is hardly and "advanced" question and you already posted a question in the "New to Java" forum 10 minutes earlier.
