Look at the following description of a problem domain:

The bank offers the following types of accounts to its customers: savings accounts, checking accounts, and money market accounts. Customers are allowed to deposit money into an account $($thereby increasing its balance$),$ withdraw money from an account $($thereby decreasing its balance$),$ and earn interest on the account. Each account has an interest rate.

Assume you are writing an application that will calculate the amount of interest earned for a bank account.

Design the UML diagram for the class.

Write the code for the class. Make sure your class has the proper constructor$($s$),$ setter and getter functions.

Simulate your class in a complete program in which you create objects from different accounts and calculate the amount of interest for a certain amount of time.
