Editor to share with you why to learn JVM, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

Why learn JVM?

Learn JVM for no more than the following reasons:

1. Program tuning

Different programs (business scenarios) require different Jvm configurations, such as setting different garbage collectors, setting memory configuration and share of new and old belts, and so on. Different configurations have different effects on the operation of programs. The default configuration of Jvm can only ensure that the program can "run", and wanting to "run well" or even "run better" is one of the most important factors in learning Jvm.

2. Troubleshoot the running problems of the program

Some programs may encounter a variety of problems when they are used online, and these problems are usually fatal, such as memory overflow, slow running of programs caused by deadlocks, and so on, and these problems are easy to be ignored in the development and small concurrent testing stages, so learning Jvm can help you sweep away the "stubborn diseases" in the system at a critical time.

3. Master the foundation and principle of program execution.

That is what many people say: we should not only "know what it is", but also "know why".

4. Avoid some mistakes when writing code

For example, avoid overloading calls to variable length parameters (specific examples will be given later).

5. Deal with the interview

I have to say that this is also one of the purposes for many people to learn, and of course it is also a positive driving force, if you understand the "catfish effect".

6. Master the general mechanism of other languages

Another powerful thing about JVM is that it can run not only Java programs, but also Scala, Clojure, Groovy, and the popular Kotlin these days. By learning JVM, you can understand the common mechanisms of these languages, and even let these languages share an ecosystem.

The above is all the contents of the article "Why to learn JVM". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
