StringList rotation

[aquafoam]

Please please help! I would appreciate it so much :)

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...

Post your attempt, post the output you got, post the exact error messages you got.

You need some kind of loop to get all rotations.
