//hence if we need to calculate hostel fees and examination fees at the point where simple factory is creating the IStudent
//then we need to modify the simple factory which is voilating the creational principle
//So wecan solve this issues by providing another layer of abstraction which takes care of computing the common interface operation
//awa specific operation related to student types
//Using Factory Method
