推荐答案

您可以参考以下代码，只需指定文件夹/目录的绝对或相对路径

You can refer to the following code, just specify absolute or relative path to your folder/dir

JFileChooser chooser = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter(
    "TXT files", "txt");
chooser.setFileFilter(filter);
chooser.setCurrentDirectory("<YOUR DIR COMES HERE>");
int returnVal = chooser.showOpenDialog(parent);
if(returnVal == JFileChooser.APPROVE_OPTION) {
   System.out.println("You chose to open this file: " +
        chooser.getSelectedFile().getName());
}
