Summary

This chapter took an in-depth look at several data structures and demonstrated their significance to a Java application’s overall performance. We embraced the essential nature of data structures for optimizing the performance of our Java applications because they can ensure that our data access, memory management, and caching are efficient. Proper use of data structures can lead to algorithm efficiency, the scalability of our solutions, and the safety of our threads.

Through code examples, we looked at nonoptimized and optimized examples of code for lists, arrays, trees, stacks, and queues. We also explored several advanced data structures and examined their added complexities. When we implement data structures properly, we can improve the predictability and consistency of our application’s performance and make our code more readable and easier to maintain.

In the next chapter, we will focus on loops and how to optimize them for increased performance regarding...
