我已经用java编写了一个gui，它允许您保存一个文件。在jfilechooser窗口中，还可以重命名、删除或创建新文件。到目前为止，始终会打开一个新的输入对话框来输入文件的新名称。如何在jfilechooser窗口中输入新文件的名称而不打开新的joptionpane inputdialog？
非常感谢

private void contextMenu() {
        try {
            popup = new JPopupMenu();
            ActionListener menuListener = new ActionListener() {
                public void actionPerformed(ActionEvent event) {
                    System.out.println("Popup menu item [" + event.getActionCommand() + "] was pressed.");
                    if (event.getActionCommand().equals("Delete")) {
                        // your logic here
                        File file = fc.getSelectedFile();
                        if (file != null) {
