QUESTION NO. 2 [5 Marks]
You are given the following UML diagram of a retail store:
Write a Java class Customer that contains the following attributes and methods:
 customerName: the name of customer
 customerAddress: the address of customer
 orderList[]: array of orders placed by the customer. Maximum of 20 orders
considered.
 nbOfOrders: the number of orders placed by the customer
 Customer(String, String): two argument constructor having name and address as its
arguments
 getCustomerName(): returns the customer name
 setCustomerName(): change the customer name
 addOrder(Order): can add orders into the orderList
 printOrders(): print out the customer and order details with total order cost
