        TreeMap<Integer, String> treemap = new TreeMap<Integer, String>();
        SortedMap<Integer, String> treemapincl = new TreeMap<Integer, String>();

        // populating tree map
        treemap.put(2, "two");
        treemap.put(1, "one");
        treemap.put(3, "three");
        treemap.put(6, "six");
        treemap.put(5, "five");

        System.out.println("Getting collection from the map");
        Collection coll = treemap.values();
        System.out.println("Value of the collection: "+coll);
    }
