java - FileFilter for JFileChooser

Question

I want to restrict a JFileChooser to select only mp3 files. But, the following code allows all file types:

FileFilter filter = new FileNameExtensionFilter("MP3 File","mp3");
fileChooser.addChoosableFileFilter(filter);
fileChooser.showOpenDialog(frame);
File file = fileChooser.getSelectedFile();

Answer 1

Try and use fileChooser.setFileFilter(filter) instead of fileChooser.addChoosableFileFilter(filter);
