Preface
Java boss detours, this is suitable for Java entry
If you are now worrying about how to learn Java, then you can take a closer look at this!
An outdated programming language-Java software development.
First of all, the above picture is divided into 4 stages in total
Stage one foundation plus improvement
In the basic stage, we must master Java basics, Mysql database, Oracle database, JDBC, Linux basics, Java8 new features, data structures and algorithms, and design patterns.
For the basic stage, what we need to master is the basics. Although it is the basics, it is hard to learn. Because it is a beginner, the basic stage will be a little difficult, but as long as you are willing to persist, these are not difficult. For Linux, data structures, algorithms and design patterns, we only need to master some basics, and there is no need to learn very thoroughly.
Phase two Java web
For JavaWeb, we need to master the knowledge: Servlet, JSP, MVC design pattern, Cookie, Session, JavBean component technology, EL expression, JSTL expression, filter, listener, file upload and download, internationalization.
Phase three SSM\SpringBoot, etc.
Phase four project phase
At last
Here is also a summary of this year’s interview: including: spring, concurrency, database, Redis, distributed, dubbo, JVM, microservices, etc. The following figure is a partial screenshot, if you need it , click here , password CSDN .
