public class JFileChooserTest 
{
 
	public static void main(String[] args) 
	{
		JFileChooser dlg = new JFileChooser();
	      dlg.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
 
	      while (true) {
	         if( dlg.showOpenDialog(null)
	               == JFileChooser.CANCEL_OPTION) return;
	         File first = dlg.getSelectedFile();
	         if (first == null) return;
	         if( dlg.showOpenDialog(null)
	               == JFileChooser.CANCEL_OPTION) return;
	         File last = dlg.getSelectedFile();
	         if (last == null) return;
 
	         System.out.println("First Path : " + first.getPath());
	         System.out.println("Last  Path : " + last.getPath());
	         System.out.println("First Name : " + first.getName());
	         System.out.println("Last  Name : " + last.getName());
	         System.out.println("First AbsolutePath : " + first.getAbsolutePath());
	         System.out.println("Last  AbsolutePath : " + last.getAbsolutePath());
 
	         System.out.println("--------------------------------------------------\n");
	      }
 
	}
}
