Java Generic Methods & Bounded Type Parameters Explained | Java Mastery Series

Published: 10 June 2026
on channel: Beat99.Academy

Master Advanced Java Generics! In this tutorial, we take our Generics skills to the next level by learning how to write our very own Generic Methods and lock down our data using Bounded Types.

We start by looking at how to apply type parameters directly to individual methods, allowing you to write highly reusable code without making the entire class generic. Then, we tackle a massive concept: Bounded Type Parameters. You will learn exactly how to use the extends keyword to set "upper bounds," which restricts exactly what kind of data is allowed to be passed in. Finally, we cover how to apply Multiple Bounds at the exact same time, and wrap up by looking at the specific rules for using bounded types inside generic classes and static methods.
