I have a problem in java swing where the user has to select a folder, so I am using the code below.

JFileChooser fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);

if(fc.showDialog(singleton, SELECT) == JFileChooser.APPROVE_OPTION) {
  File folder = fc.getSelectedFile();
  String path = folder.getPath() + File.separatorChar + MYAPPFOLDER;
}

Now there are 2 ways a user may select the folder

1. Navigate to the folder and select the folder
2. Navigate to the folder, go into the folder, and click select

Both ways work fine on windows but on OS X, I get

If I do 1 : path = Users/<username>/Desktop/MYAPPFOLDER

If I do 2 : path = Users/<username>/Desktop/Desktop/MYAPPFOLDER

How do I avoid this 2nd case?

Thanks in advance.
