Java Generics Explained: Type Parameters & Classes | Java Mastery Series
Hey guys! Welcome back to the Java Mastery Series. Today we are tackling a concept that confused me a lot when I first started: Java Generics.
We start by looking at what the code looked like before Generics existed so you can see exactly why we need them today. I'll show you how to use Type Parameters to make your code type-safe, and we will actually build our own Custom Generic Classes from scratch. We also do a side-by-side comparison of Generics vs standard Objects, and finally, why does Java block us from using primitive types (like int or double) inside Generics?
Hope this clears things up for you! Drop a comment if you get stuck on anything.
