Stuck at one part of finding duplicates in a java program. ~Line 95 within my getOverLap(), I'm stuck with combing through. I know I need to do a nested j++ within the i but I'm stuck. I know this is an arcaic way of solving this but we're confined to the material we've only covered so far. Not sure how to attach the word.txt file here but my code is below.

Thanks for any advice!

*********************************

Program requirements:

Write a program to:

1) input values from a file called words.txt. The file consists of multiple records of multiple words.

2) read all of the words into one ArrayList

3) interrogate the ArrayList and remove all duplicate words.

4) display the ArrayList with all duplicate words removed.
