Answer 1

You need a FilenameFilter. This should work for you:

FilenameFilter javaFileFilter= new FilenameFilter() {  
  @Override
  public boolean accept(File logDir, String name) {
    return name.endsWith(".java")
  }
};

Answer 2

You should look upon Filtering the list of Files in JFileChooser.

It has an example of ImageFilter.java which shows only image files in file chooser.
