运行时数据区域
程序计数器
线程私有，记录当前线程执行的字节的行号指示器。在虚拟机的概念模型里，字节码解释器工作时就是通过改变这个计数器的值来选取下一条需要执行的字节码指令。
为什么是线程私有？
在任何一个确定的时刻，一个处理器都只会执行一条线程中的指令。因此，为了线程切换之后能够回复到正确的执行位置，每条线程都需要一个独立的程序计数器，各条线程之间计数器互不影响，独立存储。所以称之为“线程私有”。
Java虚拟机栈
Java虚拟机栈是线程私有的，它的生命周期与线程相同。描述的是Java方法执行的内存模型：每个方法在执行的同时都会创建一个栈帧用于存储局部变量表，操作数栈，动态链接，方法出口等信息。
本地方法栈
本地方法栈与虚拟机栈发挥的作用非常相似的，他们之间的区别不过是虚拟机栈为虚拟机执行Java方法服务，而本地方法栈则为虚拟机使用到的Native方法服务。
Java堆(Heap)
Java堆是被所有线程共享的一块内存区域，在虚拟机启动时创建。此内存区域的唯一目的就是存放对象实例，几乎所有的对象实例都在这里分配内存。同时也被称为“GC堆”(Garbage Collected Heap) 。Java 堆可以处于物理上不连续，但逻辑上连续即可，可以通过-Xmx和-Xms控制和扩展大小。
Java方法区
方法区与Java堆一样，是各个线程共享的内存区域，它用于存储已经被虚拟机加载的类信息、常量、静态变量、即时编译后的代码等数据。它还包括运行时常量池。
