How to instantiate different object
posted 6 years ago
I have different commands. I make interface with method execute. I make 5 concrete class which implements command interface. This concrete class instantiate in different ways. some require 1 parameter, some require 2. What is the best way to design a class which takes TypeofCommand as input and instantiate correct class so that client can then simply call execute method. TypeofCommand can contains information about which class to instantiate.
