我正在尝试编写代码以在不使用集合的情况下对数组进行混洗.

我的洗牌代码

金额

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 };

public void Shuffle(){

        Random rgen = new Random();
        for (int i=0; i > amounts.length; i++) {
            int randomPosition = rgen.nextInt(amounts.length);
            double temp = amounts[i];
            amounts[i] = amounts[randomPosition];
            amounts[randomPosition] = temp;
    }
    }
