any ideas on how i should do the crypt for the following:
Suppose the key word is feather. Then first remove duplicate letters, yielding feathr, and append the other letters of the alphabet in reverse order. Now encrypt the letters as follows: abcdefghijklmnopqrstuvwxyz ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓ feathrzyxwvusqponmlkjigdcb

my first thought would be to fill an array of 26 chars, making a kind of mapping. Then, just use that mapping to encrypt what you need encrypted. Remember that you can cast chars to ints, and visa versa, such that (int)'a'=97, and (char)97='a'.
That ought to get you started.

I would suggest creating a hashtable with the initial string as the key and the string you wish to convert to as the value. For example, if a converts to t,
Hashtable table = new Hashtable(); table.put("a", "t");
You can then take each letter from the word and us it to extract the value you wish to convert to. For example,
