The class ‘warehouse’ stores the stock items as well as transactions list. The class ‘Stock Sale
Transaction’ stores the stock, price as well as quantity. The class ‘Stock Purchase transaction’
stores the stock, price as well as quantity. The class ‘stock adjustment transaction’ stores the
stock and the quantity. It helps to add or remove the stock. The class ‘stock’ stores the name,
code and quantity in stock for an item. The class ‘transactions’ is an abstract class. In class
‘program’, a menu is displayed and the user is asked to enter an option from 1 - 6 to choose
the desired action to be performed. Based on the option chosen by the user, the desired action
is performed ( using switch statement ).
Relation to key principles of object oriented
programming:
Abstraction:
It occurs when only few essential details are shown and other details are hidden from
the user. An abstract class is used for this. It cannot be used for the creation of objects.
In order to access it, it needs to be inherited from any other class.
