Well, are you going to wrap from z to a and what about caps vs lower case?

anonymous · Answer

yes from z to a ..their is no problem if it lower case or upper case

I am not sure what you mean by "their is no problem if it lower case or upper case" because to a computer they are completely different things.

In Java, a char is basically an unsigned short.  If you add one to it, it becomes the next letter.  However, if you are on z or Z, it will become something that is not what you want.  In those cases, you can just change it to a or A as needed with an if statement.

Now, if you need it to be able to account for other things than just adding one, then it takes a bit more work.

Also, with youe example you will want to itterate the string.  That means findinf the string length and then walking through it one character at a time.  You can use string.length() and string.charAt() with a loop to do this.
