Chapter 9, Problem 6P
a)
Program Plan Intro
Maintenance:
- When the system becomes operational the requirements of the user gets changed.
- Based on the requirement change request made by the end user the requirement of the system gets changed at the maintenance phase.
- The changes that are made requires maintenance activities and that are categorized in three following ways they are:
- Corrective maintenance:
- It is the maintenance that is made in response with system errors.
- Adaptive maintenance:
- It is the maintenance that is made when there is a change in the business environment.
- Perfective maintenance:
- It is the maintenance activity that is made when the system needs to be enhanced.
- Corrective maintenance:

Please answer JAVA OOP problem below:
You are working at a university that tracks students. Each student is identified by their name and faculty advisor. Each faculty advisor is identified by their name, department, and maximum number of students they can advise.
Using solid OO design principles, create a modular program that implements all the classes for the problem and also creates an implementation class that gathers user input for one student and then prints out the information gathered by creating the appropriate data definition and implementation classes. All data must be validated.
I have given the code so far:
Implementation:
import javax.swing.JOptionPane;
public class Implementation {
public static void main(String[] args) {
FacultyAdvisor facultyAdvisor = new FacultyAdvisor("Sharmin Sultana", "IT", 30);
Student student = new Student("John", facultyAdvisor);
JOptionPane.showMessageDialog(null, student.toString());
}
}

The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2.
