In 2 hours, Zhihu went crazy 27.6w times, and was finally blocked by all the big Vs.

Not long ago, an architect used his spare time to organize a "Summary of Java Core Knowledge Points" on github, which is now compiled into a PDF . The original intention is also very simple, that is, I hope to help you during the interview, reduce your burden and save Time, save unnecessary time and energy wasted. Two days ago, he shared the first draft of this interview manual in Zhihu, and under the strong suggestion of several big Vs, he optimized the manual to a certain extent. So there is the current V2.0 version of the manual. Not much nonsense, this manual is currently the first edition with the following sections:

  • Basics
  • JVM articles
  • Multithreading && Concurrency
  • Spring
  • MyBatis articles
  • SpringBoot
  • MySQL articles
  • Redis articles
  • SpringCloud
  • Nginx articles
  • MQ articles
  • Data structure and algorithm
  • Linux articles
  • Resume

To be honest, as a Java programmer, whether you need an interview or not, you should take a good look at this information. I probably slapped it again, it's really a model, and I don’t lose money when I get it~

I have prepared the above "Summary of JAVA Core Knowledge Points" for everyone, I hope it will be helpful to you who are studying!
