        TreeMap<Integer, String> treeMap = new TreeMap<Integer, String>();

        treeMap.put(1, "Cat");
        treeMap.put(2, "Dog");
        treeMap.put(4, "Apple");
        treeMap.put(3, "Ball");

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

        /*
         * Removes all of the mappings from this map. The map will be empty
         * after this call returns.
         */
        treeMap.clear();

        System.out.println("treeMap : " + treeMap);
