Implementing Thread-Safe Cache for Objects with TTL in Java 11

Designing and implementing a thread-safe cache is an essential skill to have, if you are a Java developer. Caching allows us to store frequently accessed data in memory, which can improve application performance by reducing the amount of time needed to retrieve data from slower sources. However, designing a thread-safe cache implementation can be a complex task, particularly when dealing with concurrency issues. In this article, we will explore how to design a thread-safe cache implementation that allows storing and retrieving objects with a TTL (time to live) using Java 11 concurrent data structures. We will examine the underlying principles of thread safety, TTL, and concurrent data structures, and then delve into the details of how to implement a robust and efficient cache that can handle multiple threads simultaneously. Let’s roll up our paws and get coding!
