Question

CIST 2371 Introduction to Java
Unit 04 Lab
Due Date: ________
Create a folder called Unit04 and put all your source files in this folder. You will create a UML
diagram and two Java class files and that implements the classes in the UML diagram.
Diagram
Create a UML diagram that shows an Account class and an AccountTester class. The Account class
holds the following data as Strings: account Number, type of account, card number and expire
date. Include getter and setter methods for each field. Include a multi-arg constructor that will
set all the fields. This class will NOT have a main() method. The AccountTester class file will have
only a main() method. Show the relationship between the two. The AccountTester has a "has-a"
association with the Account class.
The UML diagram should be drawn using UMLet drawing tool. The diagram should be exported as
an image and then imported into a word processing document as demonstrated in class. The
document should have your name, course assignment and date at the top like this:

The file should be an PDF formatted file and be named Unit04_<first initial><lastname>.pdf, for
example Unit04_sdoe.pdf. Any word processor can save or export to PDF.
Java
Create an Account.java class file according to your UML diagram with all the fields and methods
indicated there.
Create an AccountTester.java class file using your UML class diagram. In the main() method,
prompt the user from the console for each data field that the Account class has. Then create an
Account object and set the object's data fields using the multi-arg constructor. Then, get the data
out of each field and print it out.
Prompt the user again from the console for each data field. Create another Account object and
this time set all its fields using the setter methods. Then get the data back out again using the
getter methods like before and print out the data.
This way you will have used all the methods in the Account class at least once with one piece of
data.
What To Turn In
You will zip up the source code files in the Unit 04 folder into a zip file named Unit04_<your first
initial><your lastname>.zip. For example Tom Swift's zip file would look like this:
Unit04_tswift.zip
Turn in your PDF file as a separate submission. So you will submit two files, the PDF and the ZIP.
Be sure to test the zip file before turning it in. Copy it into a temp folder, unzip it and try to
compile and run the java file in that temp folder.
Once you are satisfied that your zip file is OK, turn it in via the Blackboard drop box for this Unit.
