Learn the implementation of commonly used data structures and classes to write programs for real-world problems.

Zero to Hero in Java

This module gives us a great understanding of the most popular data structures available in Java, like lists, linked lists, sets, and hashmaps. We'll learn how to modify data within a collection, sort a collection, and make it thread-safe. We will also cover the internal working of each Java collection so we can work with them more efficiently. By the end of this module, we'll have the confidence to use these data structures to solve various problems, no matter the situation.
