Preface
If you don’t accumulate steps, you can’t reach thousands of miles. For everyone, "accumulation" is the eternal key word in this life. In our life, no matter what industry we are in, it is very important to lay a good foundation, and it is also for programmers. in this way. Whether you are a programmer who is just learning Java or have been in the industry for many years, laying a solid foundation is the key to standing higher, just like building a house. The stronger the foundation, the longer the house will live, and you will stand. The more stable it is, it is necessary to learn the basics of Java.
Regarding the learning of Java, we must have a clear route, from basic to advanced, it is better to improve ourselves little by little. Regarding the growth of programmers, there has been a big deal recently! Tencent architect wrote a "Java Growth Cheats". After reading it, I feel that development is not that difficult.
This Java growth cheat sheet mainly covers the 4 stages of the growth of Java junior developers. After completing these 4 stages, it basically meets the basic requirements of Internet companies for developers:
- The first stage: foundation stage (Java foundation + grammar foundation + object-oriented concept, etc.)
- The second stage: the entry stage (Web development + MySQL database, etc.)
- The third stage: advanced stage (mastering the Java ecosystem + important tools + interviewers and SSMs investigated by the company)
- The fourth stage: actual combat phase (hands-on actual combat + master project specific)
The following is an explanation of the content of this "Java Growth Cheats". Due to the limited space, more detailed content cannot be displayed. However, the full PDF version can be provided for free, and those in need can be obtained for free by following the public account.
Phase 1: Foundation building
1. Java basics (introduction + Java version + Java application field + Java language features + JDK download + configuration of windows JDK environment + first Java program + professional term explanation)
2. Java grammar (output + Java data type + variable + constant + code standard degree + operator + algorithm priority + console input-Scanner)
3. Object-oriented (basic form of class + class inheritance + exception handling + package and access authority)
Stage 2: Entry stage
1. Primary exploration of Web programming (JDBC programming + Web front-end foundation + Servlet + JSP)
2. MySQL database (database principle SQL + lock + table + index and algorithm + transaction + performance optimization)
The third stage: advanced stage
1. Spring+SpringMVC+Mybatis (Introduction to Mybatis framework and +Introduction to Spring+Container+SpringIOC+AOP+SSM integration, etc.)
2. SpringBoot+SpringCloud distributed development (basic oracle entry + authority management and user management + grouping function + query + index + storage, etc.)
The fourth stage: actual combat stage
1. Business City Management System-SSM version
2. Enterprise Authority Management System
3. Actual combat of mall management system based on SpringBoot
to sum up
Learning is to change your way of thinking, change your way of thinking, and change your inherent garbage and inefficient algorithms. In short, learning allows us to change ourselves, act and practice, reflect and improve, and thus grow.
If you are on the way to learn Java now, then I believe this "Java Growth Cheats" will definitely help your study. As for how much it helps, it depends on your personal comprehension ability. However, I believe that as long as you are willing to pay, there will be rewards.
I can share this "Java Growth Cheats" with every friend who loves Java, as long as you:
