Advanced Java Concurrency

Advanced Java concurrency involves managing threads and synchronizing their interactions to achieve high-performance, thread-safe applications. Here are some key concepts and tools that are essential for advanced Java concurrency: 1. Thread Pools Using thread pools helps manage a group of worker threads to perform tasks, reducing the overhead of thread creation and destruction. The `java.util.concurrent.Executors` class provides methods to create thread pools. - **FixedThreadPool**: A pool with a fixed number of threads. - **CachedThreadPool**: A pool that creates new threads as needed but reuses previously created threads when available. - **ScheduledThreadPool**: A pool that can schedule commands to run after a given delay or execute periodically. 2. Concurrent Collections Java provides several thread-safe collections in the `java.util.concurrent` package that help avoid the complexity of manual synchronization: - **ConcurrentHashMap**: A thread-safe version of `HashMap`. - **CopyOnW...
