How to add dynamically RDF resources ?

I have a jframe  with jcombo boxes and that frame  allows to add dynamically JCombo boxes , and the items of jcombo boxes are URIs that I have extracted from an ontology ,so whenever I click on "add" button new jcombo boxes  boxes will be added to my jframe.
this is my code for adding jcomboBoxes :

I have also a button "generate RDF" for generating RDF file of the different URIS of the different jcomboBoxes,for example I want my rdf file to describe 4 URIS so I add 4 jcomboboxes to my jframe an I select for each one a diffrent URI but the problem is that it only works for the first URI and the 3 others are identical,despite I have selected different URIS.
this my code for generating rdf file  :

So how can I fix this problem ?

Without having much of the context here, my assumption would be that c4 is always set to the most recently added JComboBox due to this line:

And then c4 is later used to find the file to write:

I'm suspicious of this empty loop:

You probably meant to do something here (for example, loop through all components/combo boxes)

Yes ,c4 is the new combo box that will be added dynamically to my jframe whenever I click on the button "add",my goal is to add dynamically combo boxes then I generate rdf file to describe all the URIs of the combo boxes.
Doody calls. I would really rather that it didn't. Comfort me wise and sterile tiny ad:
