ArrayList<Students> list = new ArrayList<>();

s.setid(1);
s.setName("john");

我在javascript中的x产生了这个。即使当我尝试访问object [“ id”]例如x + =“。” + object [“ id”] +“
”;我无法。它说未定义。有什么建议吗?还是应该使用在此创建的学生模型? (不确定如何)
容器的输出:
。 {“ id”:1,“ name”:“ john”,“ year”:5.5}
。 {“ id”:2,“ name”:“ alice”,“ year”:5.5}
。 {“ id”:3,“ name”:“ nami”,“ year”:3.5}

希望这会起作用。
