Hi guy how do I randomize these numbers inside this arrays?

private double amounts[] = { 0, 0.01, 1000000, 25, 250000, 75, 50, 1000,
			200, 100, 400000, 750, 5000, 750000, 500, 100000, 300, 75000, 800,
			20, 300000, 10, 50, 750, 25, 5, 1 };

I want to randomize them without reptition so that I could insert them into this line of code so that each briefcase will hold a different value.

public void casesSetup() {	
		for (int i = 0; i < briefcase.length; i++) {

			if (i == 0) {

			} else {
				briefcase[i] = new Briefcase();
				double value = amounts[i];
				briefcase[i].setAmount(value);
				briefcase[i].setFace(i);
			}
		}
	}

Thanks in advance :D
