Question

Part I

Write a class CourseListException that extends Exception with the following constructors:

A default constructor that gives the error message "Too many courses."

A constructor that takes a string and uses this for the error message

Part II

Write a class Student with the following attributes:

Two instance variables (with corresponding getters and setters):

name - a String for the name of the student

courses - an array of Strings with length 5, holding the names of the courses the Student is taking.

A default constructor that initializes name to be "NoName".

A constructor that takes a String to set the name of the student

Two methods:

assignCourses (no input parameters or return values) - This method should ask a user to input courses from the console window until the user enters an empty line, which indicates the end of the array. If the user enters more than 5 courses, throw a CourseListException

writeStudent (no input parameters or return values) - writes the name of the student and the names of the student's courses to the console window

Part III

Write a class PartTimeStudent, a subclass of Student, for students who can take at most 2 courses. The class should include the following:

A default constructor that invokes the superclass constructor

A constructor that takes a String to set the name of the Student

An overridden assignCourses that throws a CourseListException when a user tries to assign more than 2 courses to a PartTimeStudent.

Part IV

Write a class TestStudent that does the following:

Creates a student with the name Alice

Assigns some courses to Alice

Writes the information about Alice to the console window

Creates a PartTimeStudent with the name Bob

Assigns courses to Bob

Writes the information about Bob to the console
