You ensure it will always be greater than 100 by using: (rand.nextInt(7)+1) * 100. This says, generate a random number between 0 and 6. Add 1 to that number to ensure that it can never be 0. So if it picks 0, +1 is added making it 1. If it picks 6, +1 is added making it 7, etc. This satisfies rule #1 and rule #2.

2 Ιαν 2013 · The simple algorithm would involve swapping each of the 100 elements with a random element from the 100. The number to choose would be generated from 1-100 with the above generator. For example: for (int i = 0; i < 100; i++) { swap(i, getrnd100() - 1); // - 1 for zero base! } Here is some complete code:
