java - jvm中的进程和线程与操作系统中的进程和线程的关系

Question

最近学习JVM内存模型时，看了很多帖子，大致将JVM内存分为如下几部分 从进程的角度来看，不同Java进程都要创建自己的运行时数据区吗？每个进程都有自己的执行引擎吗？

怪我咯 · Answer

That's right, according to the picture of the questioner, each process is an "execution engine". Even if it is a separate process, the runtime data area is naturally independent.

天蓬老师 · Answer

Each JVM process must start a JVM instance. Otherwise, heap sharing between processes will be messed up.
