Java并发锁的相关内容

彻底讲明白Java中眼花缭乱的各种并发锁

在互联网公司面试中，很多小伙伴都被问到过关于锁的问题。今天，我给大家一次性把Java并发锁的全家桶彻底讲明白。包括互斥锁、读写锁、重入锁、公平锁、悲观锁、自旋锁、偏向锁等等等等。视频有点长，大家一定要全部看完，保证你会醍醐灌顶。1、锁的由来在并发编程中，经常会遇到两个以上的线程访问同一个共享变量，当...

【Java并发编程九】JUC并发包下的锁

根据锁出现在Java中的时间，Java中的锁，可以分为同步锁和JUC包中的锁，同步锁指的是通过synchronized关键字来进行同步，实现对竞争资源的互斥访问的锁，同步锁的原理是：对于每一个对象，有且仅有一个同步锁，不同的线程能共同访问该同步锁。在同一个时间点，该同步锁...

Java并发 --- 锁相关问题

Java中有两种加锁的方式：一种是用synchronized关键字，另一种是用Lock接口的实现类。如果你只是想要简单的加个锁，对性能也没什么特别的要求，用synchronized关键字就足够了。自Java 5之后，才在java.util.concurrent.locks包下有了另外一种方式来实现锁...

JAVA并发-内置锁和ThreadLocal

上一篇博客讲过，当多个线程访问共享的可变变量的时候，可以使用锁来进行线程同步。那么如果线程安全性存在的3个前提条件不同时存在的话，自然就不需要考虑线程安全性了。或者说如果我们能够将某个共享变量变为局部变量，那么自然线程安全性问题就不存在了。我们把“诸如将全局变量变为局部变量”这种将某个...

Java并发显式锁和显式条件队列

一显式锁在类中利用synchronized修饰的方法或者this代码块，均使用的是类的实例锁或者类的锁。这些锁都称为内置锁。可以利用显式锁进行协调对象的访问。即ReentrantLock。这是一种可以提供无条件，可轮询，定时以及可中断的锁获取...
