public class Main {
    public static void main(String[] args) {
        // 姓名添加
        List<String> strings = new ArrayList(List.of("张三","李四","王五","赵六","阿七","老八","小九"));
        List<Integer> ints = new ArrayList(3);
        for (int i = 0; i < 3; i++) {
            Random random = new Random();
            int q = random.nextInt(5);
            if (ints.contains(q)){
                i--;
                continue;
            }
            ints.add(q);
            String s = strings.get(q);
            System.out.println(s);
        }
    }
