JAVA version: 13

Assumptions and implementations :

We have used Item class. Classes Music , Players , Instruments, Clothing,Accessories inherit Item class. Classes PaperScore, CD, Vinyl inherit Music , Classes CD Players, RecordPlayer, MP3 inherit Players. Classes Stringed and Wind inherit Instruments.Similarly, other classes are created and inherited according to the UML diagram. We have used multi-level inheritance. We have defined a Clerk class which inherits the Staff class. The clerk performs the following functions- checkRegister, goToBank, doInventory,placeOrder,openStore,cleanStore, leaveTheStore. The customer class implements buy and sell methods as per the requirements and in the UML diagram.
The Simulator class runs for 30 days doing the following in order- checkRegister , doInventory, openStore and then print the itemsLeft, the items sold and the price, the final count of money in the cashRegister and the money added to register from goToBank action.

Note :We could not fit the sub-classes of Music class in the UML because we are using Lucid Chart for creating the UML and we had exhausted the edits.
