A collection of code snippets showcasing multithreading concepts like synchronization, coordination, thread pools, and parallel processing. Enhance your understanding of concurrent programming with practical examples in Java. Ideal for beginners and experienced developers.

Introduction to Threads:

• What is a thread?
• Differences between threads and processes.
• Benefits of using threads.

Thread Basics:

• Creating and starting threads.
• Synchronization and coordination between threads.
• Thread states: new, runnable, blocked, terminated.
• Thread priorities and scheduling.

Thread Safety and Synchronization:

• Shared resources and race conditions.
• Critical sections and mutual exclusion.
• Synchronized blocks and methods.
• Volatile variables.

Inter-Thread Communication:

• Communication between threads using wait() and notify().
• Producer-consumer problem and solutions.
• Blocking queues and condition variables.

Thread Coordination:

• Joining threads.
• Thread interrupts and interruption handling.
• Thread timeouts and timed waiting.

Thread Pools:

• Introduction to thread pools.
• Executor framework in Java.
• Creating and managing thread pools.
• Benefits and drawbacks of thread pools.

Parallel Processing and Parallelism:

• Parallel programming concepts.
• Data parallelism vs. task parallelism.
• Parallel algorithms and data structures.
• Fork-Join framework in Java.

Thread Safety Mechanisms:

• Locks and mutexes.
• Semaphores and barriers.
• Atomic variables.
• Read-write locks.

Thread-Local Storage:

• Thread-local variables.
• Inheritable thread-local variables.
• Use cases and benefits of thread-local storage.

Advanced Concepts and Techniques:

• Thread starvation and deadlock.
• Thread contention and scalability.
• Thread profiling and debugging.
• Advanced synchronization primitives (e.g., CountDownLatch, CyclicBarrier).

Concurrent Collections:

• Thread-safe collections (e.g., ConcurrentHashMap, CopyOnWriteArrayList).
• Concurrent data structures (e.g., BlockingQueue, ConcurrentLinkedQueue).

Advanced Multithreading Concepts:

• Asynchronous programming and futures.
• Reactive programming and event-driven architectures.
• Actor-based concurrency models (e.g., Akka framework).
