Question
i am in need of creating a way to generate a new winning ticket after the comparison determines that the arrays are not a match. I also want to accumulate the number of times I have generated a new file and write it to a file. please use java to update existing code thank you!

Explanation / Answer
NOTE : you can do in this way, whenever the match is not found, generate a winning ticket again...in else case which means match is not found
