Java警告-JList是原始类型，必须对引用进行参数化 [英] Java warning - JList is a raw type, references must be parameterized

问题描述

有人能从Eclipse发出以下警告吗?

Can someone shed more light the following warning from Eclipse:

JList is a raw type. References to generic type JList<E> should be parameterized.

触发这一行的代码可能是:

A line of code triggering this could be:

import javax.swing.JList;
....
private JList jList = null;  // Warning on this line

推荐答案

您应将元素的类型放在<>之间，例如:

You should put the type of the elements between <>, for example:

List<String> list = new ArrayList<String>();
list.add("String 1");
list.add("Some Text");
