It can be called a masterpiece! Read through the JVM notes and easily handle the Alibaba 30K interview!

We are all experienced Java Developer , Think about why you have to learn JVM? 

[ interview ? tuning ? Pack to force ? ]

For whatever reason , Anyway, you have to learn . How to learn well ?

Java The versatility of Technology 、 Efficiency 、 Platform portability and security make it an ideal technology for network computing , From the ordinary PC To the data center 、 From game console to science supercomputer 、 From mobile phone to Internet ,Java Technology is everywhere .

JVM

It is the secret weapon that supports and realizes all this ,

It makes the Java Become a powerful 、 coincident 、 The stability of the 、 A vast operating platform .

• Java How the program works ?

• Java What role does virtual machine play in it ?

• How to make Java Programs have higher concurrency ?

many Java Programmers have questions like this .

but , But there are all kinds of  JVM  There is a lot of relevant information , From the perspective of practical application JVM It's also very rare , This makes system learning JVM  The difficulties . Can't form a complete knowledge system .

But today you are catching up with **, Xiao Bian is here to share a very comprehensive and clear explanation JVM  Notes of knowledge and experience , Content covered **：

JVM Memory structure ,HotSpot Exploring virtual machine objects , Garbage collection strategy and algorithm ,HotSpot Garbage collector , Memory allocation and recycling strategy ,JVM performance tuning , Class file structure , Class load time , The process of class loading , Class loader and other ten modules of knowledge

As well as common interview question depth analysis and other advanced methods and actual combat

This document note fills in the gap . It is from Java From a programmer's point of view , Systematically Java All kinds of knowledge involved in the process of program operation are integrated together , And with the daily work may encounter difficult cases , Lead readers to step on . On the exploration Java The journey of virtual machines , It's right Java The gospel of the vast number of readers interested in virtual machines ！
