About programmers, in addition to doing projects to improve their skills, there is a way to improve their professional skills is: more! Look! Book!

Ma has compiled a core knowledge of the path to Java advanced Architect, which is also a must-ask knowledge during the interview. The chapter also includes many knowledge points. These include the basics, Java collections, JVMS, multi-threaded concurrency, Spring Principles, microservices, Netty and RPC, Kafka, diaries, design patterns, Java algorithms, databases, Zookeeper, distributed caching, data structures, and more!

Due to the details in the PDF document is too much so only edited part of the knowledge points of the chapter rough introduction, each chapter of the small nodes there are more detailed content! The following is part of the chapter table of contents. Due to the space limit of the headlines, the detailed explanation in the table of contents cannot be listed one by one. At the end of this article, all the detailed knowledge in the following chapters can be obtained.
