In this issue, the editor will bring you about how Java programmers quickly improve their skills. The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Java itself is characterized by a wide range of knowledge, high difficulty, and a long growth cycle, and some non-subject students will find it difficult to learn, because the core Java developers that enterprises really need must be highly skilled senior engineers. So how can the friends who are learning Java improve their professional knowledge quickly? Solve more problems with less code and prepare for product maintenance with a clearer structure?

I. proficient in the use of existing frameworks

The first step in using the framework is to be familiar with and gain an in-depth understanding of the structure and content of the code. The second step is to master the rules according to usage and phenomenon after knowing how to use and use more. The third step is to make good use of it, after having a certain sense of the internal mechanism of the framework, gradually summarize and adopt the best method, that is, a more concise and clear or more efficient method.

Second, understand standard class libraries, enterprise technologies and open source projects

The existing accumulation in the Java world is already rich, and when you encounter a problem that feels like it is a common problem, it is likely that there are ready-made standard class libraries or open source projects there. A good grasp of standard class libraries and open source projects can reduce the workload and make the code structure clear and easy to understand. Enterprise technology refers to the technology within the JavaEE platform, which is mostly extracted from the existing technology accumulation of standards, such as JPA to a large extent from Hibernate, the use of enterprise technology is very good for program standardization.

The understanding of standard class libraries and open source projects can be crossed, depending on which one is used. You can also use your spare time to choose what you like to study and do experiments.

Third, write the program better

Try to follow the online code format advice and make good use of the automatic formatting function of the development tool (Eclipse). Complex conditions, loop nesting and refining into methods, make the name of the method meaningful, and try to let others see your program as if you were looking at straightforward English sentences. In pursuit of code self-annotation, we should pay attention to using words instead of pinyin as much as possible, especially the interface between modules. Today's electronic dictionaries are varied and easy to use, and making good use of them can make the code elegant and at the same time recognize a few more words.

In addition to the above advanced route, Java programmers have to update their knowledge base in real time to maintain enough core competitive advantage not to be eliminated.

This is how Java programmers quickly improve their skills. If you happen to have similar doubts, please refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
