Homework 7: People at College

Objective

In this project, youll create several classes using inheritance and polymorphism. This will require you to create abstract method and class. There wont be any exciting UI here, just some output of array data.

Structure

There are two types of College people: Students and Teachers.

All people have an ID, Name, and Email.

All IDs have validation rules, but rules differ:

Students 9 digits;

Teachers 6 alphanumeric.

For Students, we want to maintain a list of courses taken (up to 30 courses) and associated grades; we want to obtain overall grade averages as well.

For Teachers, we record courses they have taught (up to 50); we want a way to add courses to that list.

Person

-id : String

-name : String

-email : String

Constructors

+Person(id : String, name: String)

+Person(id : String, name: String, email : String )

Accessors

+getId() : String

+getName() : String

+getEmail() : String

Mutators

+setId(id : String)

+setName(name: String)

+setEmail(email : String)

Other Methods

+isValidId(id : String) : Boolean

+toString() : String

+test()

** isValidId() method should be an abstract.

Students

-courseTaken : String[30]

-courseGrades : Double[30]

-nextCourseIndex : Integer

Constructor

+ Students (id : String, name: String, email : String )

Methods

+isValidIdId(id : String) : Boolean

+courseCompletion(courseName : String, courseGrade : Double)

+getAverageGrade() : Double

+toString() : String

+test()

Teachers

-coursesTaught: String[50]

-nextCourseIndex : Integer

Constructor

+ Students (id : String, name: String, email : String )

Methods

+isValidIdId(id : String) : Boolean

+addCourseTaught (courseName : String)

+toString() : String

+test()

Code Implementation

Create a main class which creates a new instance of the Students and Teachers classes and displays all information. See examples of output.

Testing

Write test methods for each of your methods.

Test with different courses and grades to make sure your algorithms are correct.

Manual inspection will be necessary; the debugger is your friend and will be very useful here.

Submitting Your Work

Submit your .jar or .zip file

If your test method relies on test files, be sure and include them in your submission.
