Workshop 02 - IntroToOOP

Course Registration System — Workshop Assignment

---

Overview

In this assignment, you will complete a partially implemented course registration system using Object-Oriented Programming (OOP) concepts in Java.

You are provided with starter code. Your task is to complete the missing parts marked with TODO.

---

What is Already Implemented

The following parts are already implemented for you:

Course Class

• Fields: courseName, courseCode, capacity
• Constructor
• Getter methods
• Methods for managing capacity:
  • reduceCapacity()
  • increaseCapacity()

Student Class

• Fields and constructor
• Getter methods

RegistrationSystem Class

• Fields and constructor

Main Class

• Basic structure and instructions

---

Your Task (TODO Sections)

You must complete all methods marked with TODO.

---

Requirements

1. Student Class

Method: addCourse(Course c)

• Register the student in the course
• Only allow registration if the course has available capacity
• Reduce course capacity if registration is successful
• Return true if successful, otherwise false

---

Method: dropCourse(Course c)

• Remove the course from the student's registered list
• Increase course capacity after dropping
• Return true if the course was successfully removed, otherwise false

---

Method: showRegisteredCourses()

• Print all courses the student is registered in
• Display course name and course code

---

2. RegistrationSystem Class

Method: addCourseToSystem(Course c)

• Add the course to the system list

---

Method: findCourseByCode(String code)

• Search for a course using its course code
• Return the matching course if found
• Return null if no course is found

---

Method: showAllCourses()

• Print all courses in the system
• Include:
  • course name
  • course code
  • remaining capacity

---

3. Main Class

You must complete the scenario in main:

• Create at least 3 courses
• Create one student
• Create a registration system
• Add courses to the system
• Register the student in some courses
• Drop one course
• Print final results

---

Example Scenario

Create the following:

Courses:

• Advanced Programming (AP1404, capacity 2)
• Data Structures (DS2201, capacity 1)
• Database Systems (DB3301, capacity 3)

Student:

• Name: Ali
• ID: 402222001

Expected actions:

• Register the student in 2 courses
• Drop 1 course
• Print:
  • Student's registered courses
  • Remaining capacity of all courses

---

Constraints

• Do NOT modify the Course class
• Do NOT remove existing method signatures
• You must use ArrayList<Course>
• Do NOT use public fields

---

Bonus (Optional)

• Prevent duplicate course registration
• Limit the number of courses per student
• Add search by course name

---

Workflow

1. Fork the repository to your own Git account

2. Clone your forked repository

3. Create a new branch named develop:

   git checkout -b develop

4. Complete all TODO sections in the project

5. Commit your changes with meaningful commit messages

6. Push your branch to your repository:

   git push origin develop

7. Create a Pull Request from develop to main

---

Submission

• Submit the link to your Pull Request
• Your PR must be from develop → main
• Deadline: tomorrow night
• Your code must compile and run successfully
