5行代码写一个双色球生成器

    public static void main(String[] args) {
        Set<Integer> set = new TreeSet<>();
        do {
            int num = (int) (Math.random() * 33 + 1);
            set.add(num);
        } while (set.size() != 6);
        System.out.println(set + "\t " + (int) (Math.random() * 16 + 1));
    }
