Notes:

1) in case the java code does not match your class diagram then you will take zero.

2) Cheating and similar works mean zero.

3) The class diagram must be submitted as jpg image.

Problem: Consider there is an Employee class that is described by Name, Salary, and

Set of Account objects. Each Account is described by two variables: id, balance. The

Account object can be changed during execution into three possible types: saving, current

and credit. For saving account, the Employee cannot withdraw but can make deposit. For

current account, the Employee can make both withdraw and deposit. Finally, for credit

card the Employee can make withdraw with limit from credit card balance and can pay

the total expenses of credit card from balance.

There is need to create as many as filters to retrieve the objects according to the following

criteria:

1. Business Filter with all employees with Salary > 10000.

2. Rich Filter with all balance > 100,000.

3. Saving Filter.

4. Current Filter.

5. Credit Filter.

6. Retrieve all employees who are businessmen and not rich, or having saving account.

7. Retrieve all employees who are business XNOR rich.

8. Retrieve all employees who have Credit or not business and must be rich.

Questions:

1. Design the above problem as class diagram Use Design Patterns that you learned.
