Object-Oriented Java: Inheritance and Encapsulation

Codio via Coursera


Code and run your first Java program in minutes without installing anything!

This course is designed for learners with limited coding experience, providing a solid foundation of not just Java, but core Computer Science topics that can be transferred to other languages. The modules in this course cover inheritance, encapsulation, polymorphism, and other object-related topics. Completion of the prior 3 courses in this specialization is recommended.

To allow for a truly hands-on, self-paced learning experience, this course is video-free. Assignments contain short explanations with images and runnable code examples with suggested edits to explore code examples further, building a deeper understanding by doing. You'll benefit from instant feedback from a variety of assessment items along the way, gently progressing from quick understanding checks (multiple choice, fill in the blank, and un-scrambling code blocks) to small, approachable coding exercises that take minutes instead of hours.


  • Encapsulation
    • Encapsulate or bundle all related methods and data related to an object within it's class.
  • Inheritance
    • Re-use code from one class in another class by creating an inheritance relationship between the classes.
  • Polymorphism
    • Add flexibility to methods by overloading and overriding them.
  • Advanced Topics
    • Learn other topics involving classes and objects such as interfaces and creating an ArrayList of objects.
