Create a class named Course
.
Course
should define a primary constructor that accepts three values: a String?
(the department),
a String?
(the course number, and yes, this must be a String
) and an Int
(the enrollment).
You are welcome to name these properties however you like, and they should be private.
Your constructor should reject null
departments and numbers and negative enrollments.
Define a single method named equals
.
Your equals
method accepts an Any?
as a single parameter.
It should return true
if the passed object is a Course
and has the same values for the department and number,
and false
otherwise.
