        TreeSet<Integer> treeSet = new TreeSet<Integer>();

        treeSet.add(10);
        treeSet.add(50);
        treeSet.add(40);
        treeSet.add(20);
        treeSet.add(30);

        System.out.println("treeSet : " + treeSet + "\n");

        /*
         * Removes all of the elements from this set. The set will be empty
         * after this call returns.
