Lab $7$ Inheritance

Directions for completing and submitting the lab assignment:

$1.$ To complete the assignment, design an UML class diagram, and then use jGRASP or

another IDE tool, to write and compile source code for the program. Both types of files

should include your name, course number, section number and assignment number

in the upper$-$left corner.

$2.$ In java source code, you also need to:

a$.$ Indent your code.

b$.$ Follow naming rules and conventions to name class, method, variable, and

constant.

c$.$ Use proper whitespace.

d$.$ Write Javadoc comments for classes and methods in the service class, and other

comments for other statements as needed.

$3.$ Submission:

Place all files including the class diagram, and java files $($could be separated or ONE

file for one program$)$ into a folder, named FirstInitialLastName$\_$Lab#$,$ and compress

the folder as a zip file. Then submit the zip file in the drop box.

Lab Assignment $(100$ points$)$:

Do Programming Challenges $4,5,$ and $6$ on Pages $697-698$ in the textbook, and demonstrate all

of them in one application.

$1)$ Copy the four existing classes, GradedActivitity, FinalExam,

PassFailActivitity, and PassFailExam in Module $7$ Code Examples. Suppose

they were created by others, and you are unable to see source code, DO NOT modify

code in these classes. You just use them in your program for this lab.

UML class diagram:

a$.$ Your class diagram should include all of service classes $($the existing classes and

classes created by you$)$ and interface. $($The application class in the diagram is

optional$)$

b$.$ For the existing classes, here is an option: you don$$t have to list data members and

methods; just list the class name in a rectangle box and show relationships to other

classes$/$interface$.$ E$.$g$.,$
