A Good Case Study to Teach all OOP Principles in a Single Solution and Expansion to solve Problems

Wednesday 11:40am - 12:10pm, CITRENZ (Catalyst Room 5)

Object-oriented programming (OOP) is a paradigm of software programming that focuses on the creation of classes/objects and the interaction between them.

Teaching OOP is considered challenging mostly because it requires a new way of thinking about problem analysis, solution design and coding style. It can be easy for novice students to learn theoretical object-oriented concepts but most of them find it difficult when it comes to solving real-world problems.

Students struggle to apply all those four object-oriented principles together in a single solution. This paper presents a good case study – development of a library management system in Java, which can be used in practical session, to help students not only gain a better understanding of OOP principles but also apply effectively them all to create a complete application.

This paper also shows the best practices to figure out candidate classes and their relationship to draw a tightly encapsulated, loosely coupled and highly cohesive class diagram as a guideline for coding phase. The paper concludes in demonstrating how to customize this solution to solve three other different problems that have the similar solution pattern: development of online bookstore software, creation of an online rental car system, and implementation an online hotel room booking application.
