Question 1: (40 MARKS)

E-Hailing Bicycle Management System

Case Study:
An e-hailing company that rents out bicycles needs a system to manage its bicycles, users, and borrowing process. Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles).

The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles.

Requirements:

1. Add and View Bicycles:

2. Borrow Bicycles:

3. Return Bicycles

4. Display Borrowed Bicycles and Search for a bicycle

5. Create a menu-driven program to implement the above.

Sample Output:

1. Add Bicycle

2. View All Bicycles

3. Borrow Bicycle

4. Return Bicycle

5. View Borrowed Bicycles

6. Search Bicycle

7. Exit

Pentagonal Numbers

Problem Statement

Create a Java program that will display the first 40 pentagonal numbers. Hint: A pentagonal number is a
figurate number that extends the concept of triangular and square numbers to the pentagon, but, unlike the

Question3: (30 MARKS)

Passenger Rail Agency for South Africa Train Scheduling System

Problem Statement

Design and implement a train scheduling system for Prasa railway network. 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. Concurrency Handling with Multithreading i.e Use threads to simulate train operations, Each train runs as a separate thread, simulating its arrival, departure, and travel status.

3. Use ArrayList to manage train schedules for each station, Platform availability.
