Objective: Solving a design problem
Problem description: Implement a program for a currency exchange market. The main app provides
data for several clients such as web-based client, mobile and tablet. Upon any change of data in the main
app, all clients should be updated accordingly.
Write a program to show that when the main currency exchange app changes, all clients get updated.
Print messages form each client code that it has been updated due to the update of the main application.
You should submit the following folders in a zip file:
1. “1-code”: the Java source code
2. “2-App”: The compiled application
3. “3-readme”: A readme file that shows how to run your app
4. “4-report”: A report that shows:
a. The class diagram of your app
b. Comment on what is needed to be done to add new clients
c. Discussion on the advantages and disadvantages of your design solutions
No GUI, Clients are theoretical and they are classes
