【JAVA】Java并发编程中的锁升级机制

前言在多线程环境下，保障数据的安全性是至关重要的任务之一。Java提供了丰富的并发编程工具，其中锁机制是保障共享资源同步访问的关键。本文将深入探讨Java中锁的升级过程，从无锁状态到偏向锁、轻量级锁，再到重量级锁，揭示了其背后的原理与实现。正文四个级别锁在Java并发编程中，锁升级是指锁的状...

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01-Java并发机制的底层原理实现

一、处理器实现原子操作原子操作（atomic operation）意为“不可被中断的一个或一系列操作” 由于CPU的高速发展，CPU的处理速度和读写内存的速度的脱节。所以出现了存在于内存和处理器之间的高速缓存。每一个核都会去维护其自己的高速缓存，而每个核的高速缓存是互相不可见的。进而就产生了缓存一...
