java_使用List集合随机生成10个不重复的数字存入集合中,并遍历集合

public class ListDemo {
    public static void main(String[] args) {
        Random ran = new Random();
        List<Integer> list=new ArrayList<>();
        for (int i = 0; i < 10; i++) {
        	//获取随机数
            Integer random = Integer.valueOf(ran.nextInt(10));
            if (!list.contains(random)){
                list.add(random);
                continue;
            }
            i--;
        }
        System.out.println(list);

    }

}
