How do I make a large number of random arrays?

Question

I need to make an array that has 8000 random integers between values 0 - 65535 for a hash table assignment, I understand the math.random function but how do I get random numbers for such a large range of numbers? Thanks!

Answer 1

If you're in Java 8, you can write

int[] array = new Random().ints(0, 65536).limit(8000).toArray();

otherwise you'd just write something like

int[] array = new int[8000];
Random rng = new Random();
for (int i = 0; i < 8000; i++) {
  array[i] = rng.nextInt(65536);
}
