类型JList不采用参数类型< String>. [英] type JList does not take parameter type <String>

问题描述

当我尝试编译一些代码时，我不断遇到这些错误:

When I try to compile some code I keep getting these errors:

CCC.java:21: type javax.swing.JList does not take parameters
JList<String> list;

或:

CCC.java:30: type javax.swing.DefaultListModel does not take parameters
DefaultListModel<String> jobs, DefaultListModel<String> closJ) throws HeadlessException {

当我尝试删除该部分时，我遇到了大约26个相同的错误，我得到了150行错误，任何人都可以帮忙.

I have about 26 of the same error when I try to remove the section i get about 150 lines of errors can anyone help please.

推荐答案

在Java 7中将泛型添加到JList.这是

Generics were added to JList in Java 7. Here's an example from the JList documentation:

String[] data = {"one", "two", "three", "four"};
JList<String> myList = new JList<String>(data);

确保您使用的是Java 7 +.

Make sure you're using Java 7+.
