Any help appreciated. Thanks.

Welcome to JavaRanch

How are you iterating through the text? You appear to use input.hasNext() as a test in your while loop. You are never doing anything with input in that loop, so that will always return true, until your i variable falls off the end of the String and you suffer a StringIndexOutOfBoundsException.
You will have to use the length of the String to tell whether you need to continue the loop.

This is a common newbie mistake. You take too big a bite and then you end up with a heap of non-working code. Instead always develop programs in small incremental steps. Make sure everything works as expected before moving on. In this way your program will be working from start to finish. This is called Stepwise Refinement and it is the mother of all program development methods.

So start with simple program that just reads a a text file line by line and prints the lines to the screen. Then add functionality litle by little in small working increments.
 
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
