If you store the numbers in a list, then you can remove them from the list as they are found. It will need to be part of a class to store the numbers in the list, of course.

As far as generating your numbers, you can use the Math.random method or the java.util.Random class.

At some point, you will need to generate a random number bounded by the number of available numbers. You really shouldn't roll your own random number generator.

What I mean is that you will have to use a random number generator someplace in your algorithm. You have a choice, use the one in the library, or try to make your own. Unfortunately, making your own that works well is not easy, and is not a good idea.

To get an idea of what goes into a PRNG (pseudo random number generator), you can check out the source code of the SIMD-Oriented Fast Mersenne Twister.
Wow I changed my sig!
