 除了我们平时最常用的 HotSpot VM 外，还有 J9 VM、Zing VM、JRockit VM 等 JVM 。维基百科上就有常见 JVM 的对比：[Comparison of Java virtual machines](https://en.wikipedia.org/wiki/Comparison_of_Java_virtual_machines) ，感兴趣的可以去看看。并且，你可以在 [Java SE Specifications](https://docs.oracle.com/javase/specs/index.html) 上找到各个版本的 JDK 对应的 JVM 规范。

 我们需要格外注意的是 `.class->机器码` 这一步。在这一步 JVM 类加载器首先加载字节码文件，然后通过解释器逐行解释执行，这种方式的执行速度会相对比较慢。而且，有些方法和代码块是经常需要被调用的(也就是所谓的热点代码)，所以后面引进了 JIT（just-in-time compilation） 编译器，而 JIT 属于运行时编译。当 JIT 编译器完成第一次编译后，其会将字节码对应的机器码保存下来，下次可以直接使用。而我们知道，机器码的运行效率肯定是高于 Java 解释器的。这也解释了我们为什么经常会说 **Java 是编译与解释共存的语言** 。
