对于刚刚接触Java的人来说，JVM相关的知识不一定需要理解很深，对此里面的概念有一些简单的了解即可。不过对于一个有着3年以上Java经验的资深开发者来说，不会JVM几乎是不可接受的。

JVM作为java运行的基础，很难相信对于JVM一点都不了解的人可以把java语言吃得很透。在面试有超过3年Java经验的开发者的时候， JVM几乎就是一个必问的问题了。当然JVM不是唯一决定技术能力好坏的面试问题，但是可以佐证java开发能力的高低。

在JVM这个大类中，需要掌握的知识有：JVM内存模型和结构、GC原理，性能调优、调优：Thread Dump， 分析内存结构、class 二进制字节码结构、class loader 体系、class加载过程、实例创建过程、方法执行过程
