Ho开发者_如何学Pythonw filter the files by extensions (in the screen), like this example

thanks, celso.

You can use FileNameExtensionFilter to filter certain file extension in JFileChooser. The API doc for it gives a short example:

FileFilter filter = new FileNameExtensionFilter("JPEG file", "jpg", "jpeg");
JFileChooser fileChooser = new JFileChooser();
fileChooser.addChoosableFileFilter(filter);
