Java并发编程中的锁机制

Java并发编程是多线程编程的一个重要组成部分，它涉及到多个线程之间的协作和资源共享问题。在并发编程中，为了保证数据的一致性和完整性，我们需要使用锁机制来控制线程对共享资源的访问。本文将介绍Java锁机制的基本概念、种类以及使用方法。基本概念锁（Lock）是一种同步原语，用于控制多个线程对共享资源...

【Java并发编程三】Java并发机制的底层实现（二）

接下来分别举例说明同步方法和同步代码块的使用：对于普通同步方法，锁是当前方法所属的实例对象。package com.company; public class ThreadTest { public static void main(String[] args) throws Interrupted...

【Java并发编程三】Java并发机制的底层实现（一）

本篇Blog我们来学习下Java的底层对并发是如何支持的，也就是Java底层的并发机制到底是什么样的？在JVM系列的Blog我们知道，Java代码在编译后会变成Java字节码，字节码被类加载器加载到JVM里，JVM执行字节码，最终需要转化为汇编指令在CPU上执行，Java中所使用的并发机制依赖于JV...

java并发编程中的CAS机制，你理解嘛？

一、为什么需要CAS机制？为什么需要CAS机制呢？我们先从一个错误现象谈起。我们经常使用volatile关键字修饰某一个变量，表明这个变量是全局共享的一个变量，同时具有了可见性和有序性。但是却没有原子性。比如说一个常见的操作a++。这个操作其实可以细分成三个步骤：（1）从内存中读取a...
