Get the array "JTree#getSelectionPaths". Iterate over it and get each TreePath#getLastPathComponent.Remove the nodes with DefaultTreeModel#removeNodeFromParent.

For each delete-candidate node x you could check if there is a delete-candidate node y

(other than x) that has node x in its PathToRoot-array ( DefaultTreeModel#getPathToRoot(y) ).

If yes, simply set the path of x to null, so you can skip the nulls later on.
