是否可以在打开时将默认文件夹路径放入 showOpenDialog 文件名 TextArea 中？

Question

When the ShowOpenDialog window is opened, the address of the default folder path address does not automatically appear in the file name text area. The user has to choose a folder or file. However, I want to put the address of the default folder in the file name text area at starting. So the user enter image description here be able to select the default folder just by pressing the open button.

Unfortunately, the setcurrentdirectory method only shows the files and folders under the relevant folder and the filename field is empty.

The closest what I think is possible what you want is the following:

JFileChooser jFileChooser = new JFileChooser("C:\\Windows\\");
jFileChooser.setSelectedFile(new File("Downloaded Program Files"));
BasicFileChooserUI ui = (BasicFileChooserUI) jFileChooser.getUI();
ui.setFileName("C:\\Windows\\Downloaded Program Files");
jFileChooser.showOpenDialog(null);

Ie you would rather show the parent folder and then chose the folder you want to to be selected. This doesn't show you the whole path, but from the user point of view I think it's what you wanted.

Edit: I added some solution for your problem.
