  mySet.add(100);
  mySet.add(10);
  mySet.add(120);
  mySet.add(21);
  mySet.add(1);
  mySet.add(-5);
  
  System.out.println("Elements in mySet are");
  System.out.println(mySet);
 
  mySet1 = (TreeSet<Integer>)mySet.clone();
  
  System.out.println("Elements in mySet1 are");
  System.out.println(mySet1);
 }
}
