Java线程安全：同步方法、同步代码块、volatile 变量和原子变量

在多线程应用程序中，线程安全是一个非常重要的概念。线程安全是指当多个线程访问共享资源时，程序仍能正确地工作并保持一致状态。 Java 提供了多种机制来确保线程安全，包括同步方法、同步代码块、volatile 变量和原子变量等。本文将详细介绍这些机制以及如何使用它们来实现线程安全。同步方法同步方法...

尝试Java加锁新思路：原子变量和非阻塞同步算法

进年以来，并发算法领域的重点都围绕在非拥塞算法，该种算法依赖底层硬件对于原子性指令的支持，避免使用锁来维护数据一致性和多线程安全。非拥塞算法虽然在设计上更为复杂，但是拥有更好的可伸缩性和性能，被广泛应用于实现计数器、序列发生器和统计数据收集器等 1. 锁的劣势前文中曾经对比同步方法的内置锁相比和显...
