This module is designed to provide participants with an in-depth understanding of advanced object-oriented programming (OOP) principles and other essential concepts in Java programming. In this module, participants will learn about advanced OOP concepts such as inheritance, polymorphism, and encapsulation, and how to apply them to create efficient and reusable code. Participants will also learn about extension methods, interfaces, and abstract classes, which are advanced techniques used to manage classes and objects in Java. Furthermore, participants will gain an understanding of advanced topics in exception handling, such as creating custom exceptions and handling multiple exceptions, which are critical to improving the reliability and robustness of their code. Throughout the module, participants will work on several hands-on projects to reinforce their learning and improve their problem-solving skills. By the end of this module, participants will be able to apply their knowledge of advanced OOP concepts and essential Java programming concepts to develop efficient, scalable, and maintainable Java applications.
