_ JAVA COLLECTIONS FRAMEWORK

Learn Java Collections|

Explore the Java Collections Framework and Algorithms

The Collections framework gives us ready-made structures and algorithms we can use to perform common operations on groups of elements. But knowing how they work, what to use and when – that’s critical.

In this material, we’ll start by understanding why collections are useful and get a high-level overview of the class hierarchy.

Then, we’ll learn how to define different types of collections, including lists, sets, and maps, how to choose the right type for your use case, and how to work with them in practice.
