This course builds on the concepts from the introductory Java Concurrency course. It dives deeper into memory visibility, synchronization mechanisms, deadlocks, inter-thread communication, and introduces lock-free programming techniques. You will learn how to optimize synchronization, use advanced lock mechanisms, and prevent common concurrency issues such as deadlocks and race conditions.
