Gold nine silver ten, it is currently the peak season for recruitment and job hunting. Recently, I have interviewed many students who are applying for Java engineers. Many students can talk about some new technical terms, but they don’t have a thorough understanding of some core principles, especially Java. Some core basic knowledge points are not mastered enough, such as JVM, commonly used algorithms and data structures. As the so-called high-rise buildings rise on the ground, only by mastering the foundation firmly can we go further. In the face of constantly updated technology, we can quickly master it, and at the same time, we can stand out in interviews and work!
Want to stand out in an interview or job? Want to quickly master the core basic knowledge points of Java in the shortest time? I think these back-end technical system notes are very suitable for reading and reviewing by friends who are about to interview!
Due to the length of the article, only part of the catalog and content are shown here. If you need these Java back-end notes, there is a free way to get them at the end of the article!
Core basic skills
MySQL optimization and practical notes
This note sorts out the main-line knowledge of learning MySQL, such as transactions, indexes, locks, etc., and analyzes and discusses specific problems often encountered in the development process, so that you can understand the essence of the problem. Let's take a look at the catalog first!

Data Structures and Algorithms
Embarking on the road of programming means that you have chosen a life-long learning lifestyle. Every programmer has to practice eighteen martial arts, and mastering data structures and algorithms is like practicing nine-sun magic. In other words, if you master the data structure and algorithm, your internal strength practice speed will have a qualitative leap. This note is very suitable for study and review, let's take a look at the catalog first!

JVM core interview knowledge points
JVM is a hurdle in the growth of the little white Java programmers. Before learning JVM, you only need to know that the code is compiled into Class, and the virtual machine loads the Class to run. After learning JVM, you can deeply understand the process and memory of the code from compilation to loading. The creation and garbage collection of medium objects, and the rapid positioning of performance problems in daily development are of course also indispensable bonus points for interviews. This JVM note is very suitable for interview and study!

Java concurrent programming notes
Due to the birth of multi-core and multi-threaded CPUs, multi-threading and high concurrency have attracted more and more attention. As a developer, we must learn and master programming knowledge in this area. At the same time, concurrency is also one of the questions that must be asked during the interview! This concurrent study note covers the knowledge that must be asked in the interview!

Java Advanced Essentials
Distributed technology notes
As a necessary skill for back-end engineers, distributed technology is not only frequently asked in interviews, but also inevitable for promotion and salary increase. This note takes you to the 26 distributed core principles and corresponding algorithm analysis, master the 6 major distributed core technologies, and build a complete distributed core knowledge system.
Messaging middleware MQ notes
Kafka study notes
Kafka is a leader in the field of messaging engines and a heavyweight member in the big data ecosystem. This note takes you to get started with Kafka, understand its basic use, and explain the client and principles, as well as operation and maintenance and monitoring, as well as Kafka's advanced applications, to help you thoroughly understand and better use Kafka.
to sum up
Many people prepare for technical interviews and use the "Java Interview Written Questions" on the Internet, but most of these materials focus on specific questions, and the answers are short-term, and even the accuracy is questionable, not to mention analogy. Explained.
Learning is still to be down-to-earth, comb through the core and key points of Java-related technologies, and find a way to efficiently summarize your own knowledge system. It’s never too late to prepare for the 2020 Java interview and get the ideal offer.
Due to the length of the article, there are also microservices, SpringCloud, SpringBoot, high-concurrency notes, Elasticsearch and other notes that will not be displayed. If you need these Java back-end notes, friends can like + follow, and receive the through train below~
