深入解析 Java 虚拟机:内存区域、类加载与垃圾回收机制
本文介绍了 JVM 的内存区域划分、类加载过程及垃圾回收机制。内存区域包括程序计数器、堆、栈和元数据区,每个区域存储不同类型的数据。类加载过程涉及加载、验证、准备、解析和初始化五个步骤。垃圾回收机制主要在堆内存进行,通过可达性分析识别垃圾对象,并采用标记-清除、复制和标记-整理等算法进行回收。此外,还介绍了 CMS 和 G1 等垃圾回收器的特点。

(一)JVM成神路之初识虚拟机 - 探寻Java虚拟机的前世今生之秘
JVM(Java Virtual Machine)Java虚拟机的概念大家都不陌生,Java之所以可以做到“一次编译,到处运行”的跨平台性,其根本原因就在于JVM。JVM是建立在操作系统(OS)之上的,Java虚拟机屏蔽了开发人员与操作系统的直接接触,我们在通过Java编写程序时,只需要负责编写Java代码即可,关于具体的执行则会由JVM加载字节码后翻译成机械指令交给OS执行。
