Communication between Java threads (wait() in Object, join() in Thread, await()/countDown() in CountDownLatch, await() in CyclicBarrier)
Multiple threads work together to complete a task, involving inter-thread communication How to make two threads execute at the same time? private static void demo1(){<!– –> Thread A = new Thread(new Runnable(){<!– –> @Override public void run(){<!– –> printlNumber(“A”); } }); Thread B = new Thread(new Runnable(){<!– –> @Override public void run(){<!– –> printNumber(“B”); } […]
Use of Android CyclicBarrier
Allows any number of threads to wait until all cooperating threads reach a certain point, and then all threads continue execution from that point Constructor public CyclicBarrier(int parties) {<!– –> this(parties, null); } public CyclicBarrier(int parties, Runnable barrierAction) {<!– –> if (parties <= 0) throw new IllegalArgumentException(); this.parties = parties; this.count = parties; this.barrierCommand = […]
CyclicBarrier for Aqs.
Today we will learn about the “outer disciple” of the AQS family: CyclicBarrier. Why is Cyclic Barrier said to be the “outer disciple” of the AQS family? That’s because CyclicBarrier itself and the internal class Generation do not inherit AQS, but the source code implementation relies heavily on ReentrantLock, a member of the AQS family. […]
JUC concurrent programming synchronizer (Semaphore, CountDownLatch, CyclicBarrier, Exchanger, CompletableFuture) with related interview questions
Directory 1.Semaphore (resource scheduling) 2.CountDownLatch (child thread priority) 3.CyclicBarrier (fence) 4. Exchanger (public exchange area) 5. CompletableFuture (asynchronous programming) 1.Semaphore (resource scheduling) Since the system resources are not unlimited, if the multi-thread requests are endless, it will cause a very heavy burden on the system. Semaphore resource scheduling is introduced in JUC, which allows threads […]
