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 FileNameExten         


        

Answer 1

Try:

FileFilter filter = new FileNameExtensionFilter("My mp3 description", "mp3");

The first argument is simply a description of the FileNameExtensionFilter - and since the second argument is var args, you can leave it out like you did, effectively meaning there is no filter.
