Welcome to JavaRanch

There are ways of doing it with JFileChooser; you can add a filter. There is a section in the Java Tutorials about that.
There are methods in the File class; you can use the isDirectory method to find whether an object represents a directory, then the list method, then on each of the Strings the lastIndexOf or endsWith methods.

Other people will doubtless think of other ways to do it.
