   map.put(Months.January,"1");  
   map.put(Months.February,"2");  
   map.put(Months.March,"3");     
   map.put(Months.April,"4");   
   // print the map
   System.out.println("Map: "+map);
   // get the value for Days.Monday
   String value = map.get(Months.March);
   System.out.println("Months.March value: "+value);
   System.out.println("Months.May value: "+map.get(Months.May));
