Swing JTree with Checkbox and JFileChooser

问题

By using JFileChooser I am able to select file and folders getting JList with File Objects and I am showing it with checkbox. Now my requirement is like I want to show the selected file and folder in tree structure with checkbox and the checkbox should be only for root elements not for all child elements.

Example : For Example, I selected folders ABC and PQR which containt sub folders and few files now on UI It should be display

Checkbox1 ABC--
          --SubFolders
          .           --SubFolder
          .                      --Files
          --Files
Checkbox2 PQR--
          --SubFolders
          .           --SubFolder
          .                      --Files
          --Files

Sounds a bit complicated... as far as the tree goes, there's an online post of code from the OReilly Java Cookbook that might help you:
