If you want to get an offer of 10k-40k, these skills are essential. Do you understand that you are a programmer?

Summarized a Java architect's skill tree, I hope it will be helpful to Java programming students

Technical points of Java programming:

Note: The following is mainly my personal summary method experience (interview study and writing notes)

01 Sort out the knowledge system and learn to check for gaps

Regarding the sorting out of the knowledge system, I personally mainly divide it into the following 5 parts. If we break through these 5 parts step by step in a targeted manner, then there is basically no problem in getting the interview done.

The bottom layer of Java: the principle of TCP, the bottom layer principle of JVM tuning, the in-depth knowledge of the bottom layer of Java, the principle of Java concurrent programming
Performance tuning: JVM tuning, MySQL performance tuning, Nginx tuning, Tomcat tuning
Java Concurrent Programming: Threads, Locks, Thread Pools, Compilation Collection, JUC, Asynchronous Programming
Framework principle source code: Spring, pringMVC, Mybatis, Springboot, SpringSecurity source code
Middleware: message middleware, distributed storage middleware, distributed framework, distributed search

02 Break down one by one according to the main points (review according to the content of the outline)

03 Finally, look at the interview questions to draw inferences (scrub the questions, brush the questions, and say important things three times)

There are also methods for interview questions. It is suggested that it is best to proceed according to the topic, and then from basic to advanced, from shallow to deep, the effect will be better.

The above information has been organized

As a programmer, phased learning is essential, and it needs to maintain a certain degree of continuity. This time, during this phase, I have systematically reviewed some key knowledge points. On the one hand, I have consolidated my knowledge. On the other hand, it also improves the breadth and depth of its knowledge.
