Question

How do you provide a seed for a java random generator?
Random generator = new Random(2002334);
Does this produce the same number every time the random generator is called and does it matter what number you use as a seed?

Answer 1

By creating an instance of the Random class.

Random rand = new Random(42);
int x = rand.nextInt(); // will always be the same

You can also use the setSeed method to (re-)set the seed on an already created Random instance:

rand.setSeed(42);
int x = rand.nextInt(); // will be the same again
