Threads And Concurrency Questions
There are several ways to achieve thread synchronization in Java:
1. Synchronized keyword: The synchronized keyword can be used to create synchronized blocks or methods. It ensures that only one thread can access the synchronized code block or method at a time.
2. ReentrantLock class: The ReentrantLock class provides a more flexible way of achieving thread synchronization. It allows multiple locks and conditions, and provides additional features like fairness and interruptible locks.
3. Semaphore class: The Semaphore class can be used to control the number of threads that can access a particular resource. It maintains a set of permits and allows threads to acquire or release these permits.
4. CountDownLatch class: The CountDownLatch class allows one or more threads to wait until a set of operations being performed in other threads completes. It is initialized with a count, and each thread calls the countDown() method to decrement the count until it reaches zero.
5. CyclicBarrier class: The CyclicBarrier class allows a set of threads to wait for each other to reach a common barrier point. It is initialized with a count, and each thread calls the await() method to wait until all threads have reached the barrier.
6. BlockingQueue interface: The BlockingQueue interface provides thread-safe operations for adding and removing elements from a queue. It can be used to coordinate the communication between producer and consumer threads.
These are some of the ways to achieve thread synchronization in Java, and the choice of synchronization mechanism depends on the specific requirements of the application.
