multithreading

Multithreading allows a Java application to perform multiple tasks concurrently using multiple threads. This section covers thread creation, thread lifecycle, synchronization, locks, volatile, race conditions, deadlocks, executors, thread pools, and concurrent collections. You’ll learn how threads share data and how to write thread-safe code. The section also introduces modern concurrency concepts such as CompletableFuture and virtual threads where relevant. Understanding multithreading is essential for building high-performance and scalable Java applications.
