Dice Generator Probability

This application looks to be coded properly, but every time I run it, 1-4 "random" dice values are never landed on. Is this a bug with random and how long it takes to start at a new seed, or what?

You're creating a new instance of Random every iteration through the loop, which probably has something to do with it. Either initialize and use a single Random object for all rolls, or, if you need a new one each time for some reason, use SecureRandom() which gives cryptographically secure "true" random numbers.
