                }

        }
    }

Above is the much editied code, finally i got the files to print to the terminal window, then i added the much need if statment and nothing to the window again


can some one complie it or till me what the problem is?

Can you give more detail than just "I added "if" and it doesn't work"? Which "if" are you talking about?

You have to show a bit more effort than just provide a code dump, and a "adding an if" and it doesn't work.

Ohh ok, no problem,


well the "if" statement on Lines 50/51


after adding that if statment I got nothing to the terminal window, would it should do is compute the files that make up the two ArrayLists


it should essentially filet out files that are equal in size, but different in hash code value


its like its filtered out everything


or maybe im referecing the arraylist items wrong or theres nothing in the array lists i dont know whats gone wrong, as it all compiles

[Imad Ali]

it does print with if statement sorry i got another class mixed up



this is the output (some of it)
