my second if(output) loop, will not stop looping. if there are any suggestions in troubleshooting the loop?

That's a ton of code, but I think the problem might just be the condition in your while loop. You have:

while (!inputFile.equals("exit") || (!outputFile.equals("exit")))

So the loop will exit if you've put in exit for both the input file and the output file. However, you only check for input once, when the two files are first used. If you want the loop to take two new file names every time, you'll need to add that at the end of the while loop, something like harshit suggested. If you add String inputFile = inputFileName(); and String outputFile = outputFileName();at the end of the while loop, you'll enter new file names each time the loop occurs and you should be able to exit it.

thats because your ouptutFileName doesnt change and its not if loop it is while loop going infinite.. i guess before the end of the while loop you should be taking the input from the console again . so just at the end of while loop you should do

String inputFile = inputFileName();
String outputFile = outputFileName();
