Static factory method

• Earlier factory was returning new Object whenever it was called to provide the child Object, now this has been replaced to provide object from static collection, this in turns help in reduction of memory foot-print, for example we ask factory method to provide Elf's Axe for Five times, earlier it used to generate 5 different object and return, now it will return Single object for each call.
• This will help in reduction of memory foot of the application
