One of the most complex and powerful functionalities offered by the Java concurrency API is the ability to execute concurrent-phased tasks using the Phaser class. This mechanism is useful when we have some concurrent tasks divided into steps. The Pha…
The Java concurrency API provides a class that allows one or more threads to wait until a set of operations are made. It's the CountDownLatch class. This class is initialized with an integer number, which is the number of operations the threads are g…
The Java concurrency API provides a synchronizing utility that allows the synchronization of two or more threads in a determined point. It's the CyclicBarrier class. This class is similar to the CountDownLatch class, but presents some differences tha…
The Phaser class provides a method that is executed each time the phaser changes the phase. It's the onAdvance() method. It receives two parameters: the number of the current phase and the number of registered participants; it returns a Boolean value…
粗略看完<Java Concurrency in Practice>这部书,确实是多线程/并发编程的一本好书.里面对各种并发的技术解释得比较透彻,虽然是面向Java的,但很多概念在其他语言的并发编程中,也可以用到.因此,开始写下其读书笔记,归纳总结. 闲话少说,从第十章开始,先上思维导图: 本章的重点,是死锁以及死锁的分析和避免方法. 10.1.1 锁的顺序产生死锁: public class WorkerThread implements Runnable{ private LeftRigh…
