推荐答案

正如@Andreas_D所说，以数据为中心，更抽象的ListModel是解决方案.这可以是 DefaultListModel .您应该在JList中显式设置模型. 因此(感谢@kleopatra发表评论):

As @Andreas_D said, the data centered, more abstract ListModel is the solution. This can be a DefaultListModel. You should explicitly set the model in the JList. So (thanks to comment by @kleopatra):

DefaultListModel model = (DefaultListModel) jlist.getModel();
int selectedIndex = jlist.getSelectedIndex();
if (selectedIndex != -1) {
    model.remove(selectedIndex);
}

DefaultListModel中有几种remove...方法. 顺便说一句，这是一个好问题，因为API(ListModel)中没有即时解决方案.

There are several remove... methods in DefaultListModel. By the way, this is a good question, as there is no immediate solution in the API (ListModel).
