You will develop a simple shopping mall program which keeps the customer, product, and order information. You have to provide a demo program named OnlineDemo.java and all other classes.

Need to have these four (4) classes: onlineDemo.java, customer.java, order.java, and product.java classes

Sample OUTPUT of Program 1: This is a sample run of your demo program. Your program has to display output messages as below. Again, your demo program, OnlineDemo.java, has to have the main() method to run the whole program. We do not provide any demo program to test your program.
