computer Programming :
Objective and Overview Lab Marks: out of 20 Learn about Object Composition and Arrays of Objects / Array Lists Testing java Classes. Using GUI to test Java Classes Grading Rules You have to solve all the exercises of each Lab . code free of anysyntax error: 20% Group Submission Code runs and free of any runtime errors: 10% code naming conventions shall be respected (variable names, formatting Your code should be tidy and commented (well formatted), 10% (4 marks from 20) (2 marks from 20) (2 marks from 20) (2 marks from 20) (10 marks from 20) ), 10% . · Your code works and gives the expected results or solution, 50% Submission Rules " Zip your NetBeans Project named Lab121ldx (X is your id 201612345) and submit using link provided in Blackboard Lab published on the week of 08/04/2017, submission after 5 to 7 days The deadline is displayed when you click on the submission link. Any late submission will reduce your grade You have always between 5 days and 1 week deadline depending on the Lab. All the Labs are done in groups of 02 students. Plagiarism means zero and administrative consequences from the college and university Exercise 1 (20 marks) CIT College of Information technology has students, faculty, courses and departments. You are asked to create a program to manage all these information's. Create a class CIT to represents the following: Array of Students, each student is represented by class Student Array of Faculty, each faculty is represented by class Faculty Array of Course, each course is represented by class Course Array of the courses the students took or is taking. Represented by the class StudentCourse. . Classes to be created and used in the CIT Class Student which is composed by: students ID, person, address and phone and array of courses Person represented by: first name, last name, date of birth, City of birth . .Explanation / Answer
I'm printing here all the code for the classes needed first, then CITDemo class which is incomplete as the question requires huge amount of time. I could create classes and fill up some data. I think the operations on the data are straight forward.
Please create a separate file for each of these classes. Dont forget to keep them in the same package "com.cit.college".

this.city = city;
}
public String getAll(){
return toString();
}
public void setAll(int homeNumber, String street, String city){
this.homeNumber = homeNumber;
this.street = street;
this.city = city;
}
@Override
public String toString() {
