Shuffling two arrays in Java

Question

Hello,

I have an assignment that creates a quiz for user. I'm supposed to shuffle the questions in a random order. I can't figure out how to shuffle the array of questions to correctly match up with the array of answers. Any help would be appreciated.
Thank you.

Answer 1

@Jacob solution works great and straightforward but I would like to offer another thought:-

If different piece of information are inter-related, combining it into a single object would be a better option with respect to OOP.

Quiz ➡ question, answer

Therefore if you have a List of Quiz, simply calling the shuffle() method from java.utils.Collection will do the job. Hopefully it helps! 😉

Answer 2

Let’s say there are 5 items to shuffle. You could create a third array of integers where you put random numbers from 0 to 4, and retry if there is a duplicate. Now, you can reorganize the other 2 arrays according to that order.

Thank you
