Instead of defining a HashMap object, I've defined a Map object:
Map<String, Object> myHashMap = new HashMap<String, Object>();

After populating the HasMap...
Then I've used another Map as a TreeMap and its putAll method to get
all the elements of the HashMap directly in sorted order:
// Display it sorted
Map<String, Object> myTreeMap = new TreeMap<String, Object>();
myTreeMap.putAll(myHashMap);
System.out.println("My hash map in sorted order" + myTreeMap);
