so i have ran into a small problem while designing an API which can restore data from the selected List check view from DropBox-

The checkList gets the List of deleted data and stores in another list called deletedItems ,so when the deleted data gets a selected over a checkList it is stored in deltedItems.

checkList = new ListView();
 Label labelresponse= new Label();
 checkList.setPadding(new Insets(10, 10, 10, 10));
 checkList.setMaxHeight(400);
 checkList.setMaxWidth(280);
 checkList.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);

 checkList.setCellFactory(CheckBoxListCell.forListView(new Callback<String, ObservableValue<Boolean>>() 
 @Override
 public ObservableValue<Boolean> call(String item) 
 BooleanProperty observable = new SimpleBooleanProperty();
 observable.addListener((ObservableValue<? extends Boolean> obs, Boolean wasSelected, Boolean isNowSelected) -> 
 //System.out.println("Check box for " + checkList+ " changed from " + wasSelected + " to " + isNowSelected);
 if(isNowSelected) 
 deletedItems.add(item);
 else
 deletedItems.remove(item);
 
 System.out.println(deletedItems + "n");
 System.out.println(deletedItems.size() + "n");
 );
 observable.set(deletedItems.contains(item));
 deletedItems.addListener((SetChangeListener.Change<? extends String> c) ->
 observable.set(deletedItems.contains(item)));


 return observable ;
 
 ));

Now i want method that will restore the the selected deletedItems. But i can't seem to implement it properly. I do found a java Code on how to Restore data in DropBox

public void dataRestoreFromList() throws DbxException 
 FileMetadata revision = revisions.get(0);
 revision.getRev();
 String rPath = revision.getPathLower();
 getDbxCleint().files().restore(rPath, revision.getRev());
 

is there anyway i can restore the data from deletedItems Set using this method ?
