Answer 1

Your array n should be declared as:

char[] n = new char[str.length()];

That creates an array with the exact size needed to put all your String's characters in it.

An ArrayIndexOutOfBoundsException is thrown when you access an illegal index of the array, in this case I suspect your array is smaller than the length of the String.
