if (Character.isWhitespace(inputTextArray[inputTextArray.length - 1]))
inputTextArray[inputTextArray.length - 1] = null;
how can i remove the value out of the position of the array im in.

Answer 1

Once you've created an array, its size is fixed forever, so you cannot remove elements from it.
What you will need to do is to construct a new array that contains the same text, but with the white space ommitted. Since you won't know how big the new array is until you've gone through the first one, you need something whose size is not fixed at the beginning.
Given that you're dealing with text, I'd suggest you take a look at StringBuffer.
