Summary
Concurrency is a fundamental concept in modern software development, allowing applications to perform multiple tasks simultaneously, and efficiently utilizing system resources. In this chapter, we explored various aspects of concurrent programming in Java, from basic thread creation and management to advanced techniques for handling synchronization and shared data.
We started by introducing concurrency and its importance, followed by walking through creating threads using the Thread class, the Runnable interface, and implementing the Runnable interface with lambda expressions. We then moved on to two thread management methods: sleep() and join(). Next, we talked about ExecutorService, which provides a higher level of abstraction for managing thread execution and made our lives a little easier (after making it harder first).
A crucial aspect of concurrent programming is avoiding data races. We demonstrated a data race example and discussed strategies to resolve them, including...
