- Course Overview
- Embark on a comprehensive journey into the foundational principles of Java Object-Oriented Programming (OOP), meticulously designed for aspiring and intermediate Java developers.
- This 3.5-hour immersive program, updated in January 2026, offers a dynamic blend of theoretical concepts and practical application, ensuring a robust understanding of OOP paradigms.
- With a stellar 4.65/5 rating from over 25,911 students, this course is a proven pathway to mastering OOP in Java.
- Explore the core pillars of OOP: Classes, which serve as blueprints for creating objects, and Objects, the tangible instances of these blueprints, understanding their creation, manipulation, and lifecycle.
- Delve into Encapsulation, the mechanism of bundling data and methods within a single unit, and learn how it promotes data integrity and modularity.
- Master Inheritance, a powerful concept that allows new classes to inherit properties and behaviors from existing ones, fostering code reusability and hierarchical relationships.
- Uncover the nuances of Polymorphism, enabling objects of different classes to respond to the same method call in their own unique ways, leading to flexible and extensible code.
- Gain insights into advanced OOP design principles like the SOLID principles, crucial for building maintainable, scalable, and robust software systems.
- The course is structured to progressively build your OOP expertise, starting with fundamental concepts and moving towards more complex design patterns and best practices.
- Each module is accompanied by practical exercises designed to solidify your understanding and provide hands-on experience.
- Target Audience
- Beginners looking to grasp the core concepts of object-oriented programming in Java.
- Developers transitioning from procedural programming languages to an object-oriented paradigm.
- Intermediate Java programmers seeking to deepen their understanding of OOP principles and best practices.
- Students preparing for Java development roles or certifications.
- Anyone interested in building well-structured, maintainable, and scalable Java applications.
- Skills Covered / Tools Used
