如何在JList中的String旁边添加JCheckBox，并允许它选择并打开存储在文件夹中的多个文件而不使用ctrl键？

Question

我对Netbeans界面还很陌生，但我想请求一些编码方面的帮助。我的目的是创建一个GUI，在其中填充存储在我已成功的指定目录中的文件。

但是，现在我希望在核对清单中显示的文件名旁边包含复选框。因此，当用户选中复选框或复选框时，它可以打开存储在文件夹中并显示在JList上的文件。

如何通过勾选复选框而不使用ctrl键来允许用户选择和打开多个文件？

以下是我的代码。

   public status() {
        initComponents();

          DefaultListModel model1 = new DefaultListModel();
         File o = new File("c:/Users/zikai/Desktop/test");

         File[] yourFileList = o.listFiles();

         jList1.setCellRenderer(new CheckboxListCellRenderer());
        for(File f : yourFileList) {
            model1.addElement(/*ch[i]*/ f.getName());

        }
        jList1.setModel(model1);
    }
