   // adding in the tree
   tree.add(12);
   tree.add(13);
   tree.add(14);
     
   // cloning tree into clinetree
   clonetree = (TreeSet)tree.clone();  
 
   // creating iterator
   Iterator iterator;
   iterator = clonetree.iterator();
     
   // displaying the clonetree data
   System.out.println("Tree set data: ");
