Have you ever stopped to think: after x years of Java development, why are your skills so much worse than others?
In fact, the level of technical level and personal intelligence quotient is not related (after all, we can do Java programming development is not bad), mainly with the degree of diligence, improve methods.
Diligence, needless to say, depends on self-supervision and self-control. Here we will talk in detail about the method of promotion, after all, a good method of promotion can make you get twice the result with half the effort. What are some of the most effective ways to become a Java senior engineer?
Here are three things you should pay attention to:
Understand the basic technology
Develop a good habit of reading source code
Have long – term technical learning plan
Now, let’s take a look at each one, especially method 3.
1. Understand the basics
Basic technology is the common foundation of all kinds of upper technology. Understanding the underlying technologies is a way to better understand how applications work and evolve better products based on those underlying technologies. Many distributed system architectures, as well as high availability, high performance, and high concurrency solutions, can be found in basic technologies. Therefore, the study of basic technology can better master the technology of higher dimensions.
Many people will think that the underlying technologies are profound, from languages, programming paradigms, algorithms and data structures, computer principles, networks, databases, distributed technologies, and so on, how can they have the time to master so many things? This really needs the perseverance of continuous learning. Now many technical masters are still consolidating and expanding their underlying technology, so there is no reason for them to ignore this piece, isn’t it?
2. Develop a good habit of reading source code
Read the source code, especially for any third-party libraries you are using. Do not interview, what source code have not learned, the reason is that business is too busy, more even say “I feel useless”.
Reading the source code should answer two questions: what problem is to be solved + how is it implemented? When looking at a whole project or a module or function, we should always look at these two problems. After reading these two questions can answer, is effective.
Here’s what you should do when reading the source code:
Background check: read the official website and Wikipedia to learn about the main features, which projects they are used for and how they are used
Use frameworks: at least make a small demo with follow “Get Started”.
Compile and debug where possible. There is almost no code that can be debugged that is unreadable
Learn some design patterns. So when you see proxy, Builder, factory in the name, you get it
Horizontal layer, longitudinal block. The code is modular, some of it is Core, some of it is Util, Parser, stuff like that, so you know what layer you’re looking at, what piece you’re looking at. Some small projects are not clearly layered and do not have to be forced
Note: it is not only the grammatical skills that should be looked at, but also the ideas and principles of design. Easy to know, easy to do, put a good habit of reading source code on the agenda!
Have long-term technical learning plan
The path to Java advancement is guided by a long-term learning plan. You can develop a systematic learning path that will help you improve your overall skills. Of course, almost every Java programmer has a dream of becoming an architect.
The following is a small series of carefully systematic arrangement of a set of technical system diagram of the idea, I hope to let more students in the road of technology can take some detours.
One: architect aesthetics
Learning Java technology system, design patterns, popular framework and components, common design patterns, coding essential, Spring5, do application essential latest framework, MyBatis, play database essential components……
DevOps (Architect toolkit)
Maven, Project management, Jenkins, Continuous integration, Sonar, code quality management, Git, version management, Agile development…
Three: Essential Technology Stack for Architects (Distributed Architecture)
High concurrency, high availability, massive data, no distributed architecture knowledge is certainly not to play, to understand distributed, distributed architecture principle, distributed architecture strategy, distributed middleware, distributed architecture combat and so on
4. Architecture Technology (Microservices Architecture)
As businesses become more complex and services are layered, microservices architecture is the only way to upgrade the architecture. Examples: microservices framework, Spring Cloud, Docker and virtualization, microservices architecture
Five: performance optimization
Any PPT architect who deviates from the details is a bully who can manipulate from the top to the bottom to solve first-line performance problems such as performance metrics, JVM tuning, Web tuning, DB tuning, etc….
Six: Architecture requirements (Basic knowledge)
From architectural design, to application layer tuning, to in-depth understanding of the underlying principles, solid Java basic skills to become a master master: memory model, concurrent mode, threading model, lock details and so on
These technologies are essential to enter the large Internet, and they are all technical knowledge that must be accessed.
Interested can come to get some architecture video materials to learn, systematic learning to enhance their technology stack
So how can these techniques be learned in depth?
1. Those with 1-5 work experience do not know where to start in the face of the current popular technology and need to break the technical bottleneck.
2. I have been in the company for a long time and have been comfortable, but I hit a wall in the interview when I changed my job. Need to study in a short time, job-hopping to get a high salary.
3. If you have no working experience, but have a solid foundation, familiar with Java working mechanism, design ideas and common Java development framework.
4, feel very good B, general needs can be done. But without systematization of knowledge points learned, it is difficult to continue to break through in the field of technology.
5. Group Number: Advanced architecture group705127209Note good information!
6. Ali Java senior bull live explain knowledge points, share knowledge, sorting out and summarizing years of work experience, with everyone to establish their own technical system and technical knowledge in a comprehensive and scientific way!
7. Don’t add white
