Inheritance in Java: Computer Science 101 | Outlier.org

Learn about inheritance in Java in this easy-to-understand Introduction. We’ll go over classes and inheritance in object-oriented design, including defining attributes and behavior, and considering overlapping classes.

As an associate teaching professor at Illinois Tech for over two decades, Professor Michael Lee has inspired an entire generation of computer science students. He is passionate about attracting more students of diverse backgrounds into the field of computer science and fostering a kinder, more inclusive future coded by the CS students of today.
