3.7 Adding a shuffle(char[]) method

Juppies 2 by Dr Heinz M. Kabutz

Unfortunately we only have a method for shuffling int[], but the char[] will work in the exact same way. We copy and paste the shuffle(int[]) method contents into our new shuffle(char[]) and all that we need to do is change the name of the variable to letters instead of indexes. By double-clicking on the word, we select the whole word and that makes it quick to replace the words.
