Question

Can you produce infinite random numbers using randGen.nextInt()?

Answer 1

Yes, you can use a while loop with randGen.nextInt in order to constantly be creating new random numbers.

Answer 2

You certainly can keep generating an infinite number of pseudo-random numbers, but as a side note, eventually the sequence will repeat and you will start getting the same sequence of numbers again, because of the algorithm used to generate the numbers.

However, this will only happen after many billions of numbers, and as a practical matter, it shouldn't affect any Java code that you write...
