EECS2030: LAB 7 Due: Sun 27th , XXXXXXXXXX:59 pm
The purpose of this lab is to practice working with interfaces, abstract classes,
defining and using customized exceptions and obligatory methods.
1. Setup
Please download Lab7.zip that is attached to this description.
• Open eclipse.
• Click on File and select Import.
• Choose Existing Projects into Workspace and click Next.
• Click on Select Archive File and then Browse. Find Lab7.zip and
click Finish.
• Please make sure that you do not already have a project called
EECs2030_Lab7, otherwise, eclipse cannot import it for you.
You should see two files, one is called Account.java and one
AccountTester.java.
Please note that AccountTester.java shows several compiler e
ors. This is
expected as the code in Account.java has not been implemented yet.
2. JavaDoc generation
The javaDoc has been written for you only for the superclass. For the subclass,
which you are going to write from scratch, you need to write the javaDoc
yourself.
When you finished, all you need to do is to generate it as an HTML file to make
it easier for navigation. For this, right click on Account.java -> export ->
javaDoc -> Next. It will ask you for the location in which you want to store
the documentation. Enter the path and then click Finish.
If you look at the location in which you stored the documentation, you willl
see there is a file called index.html. Clicking on this file, shows the
documentation of the project in your
owser.
3. Programming Task
A bank account can have many types, including cu
ent, saving, investment
and so on. In this lab, we are going to work with cu
ent accounts only. Your
job for this lab is to look at the UML below and implement the code that
conforms with this UML.
An account can be deposited or withdrawn by some amounts of money. This
is done by two methods called deposit and withdraw respectively.
It is not possible to withdraw more money than the balance of the account.
If a client tries to do so, an exception called NotEnoughMoneyException is
thrown. This is a user-defined exception.
Also, it is not possible to withdraw money more than what maxTransferable
shows. If a client tries to do so an exception called
TransferNotAllowedException is thrown. This is also a user-defined
exception, which is the base class (i.e., superclass) of
NotEnoughMoneyException.
It is possible that some amount of money is withdrawn from the account and
deposited to another. This is done by transferFrom method. This method
may throw two exceptions if either more than the balance or maximum
amount allowed for the transfer, is withdrawn.
Your job is to implement all the classes and the methods that you see in the
UML.
4. Submit
You only submit one file that is called Account.java via eClass by clicking
on the lab link.
You do not need to submit the tester or HTML files.
