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.

Data Structures in Java

Congratulations! You have successfully completed the “Data Structures in Java” module.

## Summary

In this module, we covered the most commonly used data structures and classes in Java. The module provides a basic introduction and a few challenges for the following data structures, lists, linked lists, sets, and hashmaps. We also covered the internal working of each Java collection so we could work with them more efficiently. Additionally, we discussed how to modify data within a collection, sort a collection, and make it thread-safe. We now have the skills to solve various problems in Java, no matter the data structure.

## What’s next?
Now that we have learned about different data structures in Java, we will work on some practical projects in the next module, “Projects and Practice in Java.”
