10 Tips to Become an Outstanding Java Programmer

If you are a Java programmer who is passionate about technology, then the following 10 points can make you stand out among many Java developers.

1. Have a solid foundation and deep understanding of OO principles

For Java programmers, a deep understanding of the concept of Object Oriented Programming is a must. Without a solid foundation in OOPS, you cannot appreciate the beauty of object-oriented programming languages ​​like Java. Learning the definition of OO principles is not very useful. The key is to learn how to apply these principles to design solutions in an OO way. Therefore, we should have a good understanding of object modeling, inheritance, polymorphism, and design patterns.

2. Master the core API

If you don't know the language structure and core API, then no matter how strong your theoretical knowledge is, you can't make a forest of trees. In Java, we can only have strong practical experience with core APIs such as java.lang.*, I/O, exceptions, collections, generics, threads, JDBC, etc. When it comes to web application development, no matter how much you use the framework related to Servlet, JSP is a must.

3. Keep coding

Lu You once said, "What you learn from books is always shallow, and you must practice to fully understand it." It's easy to come up with a solution in theory, but when you really implement it, you will realize how difficult the problem is. At this point, you will understand the language limitations of the coding process and design the best practical solution. Therefore, keep coding.

4. Subscribe to the community forum

We are not alone. Many people are working on the same technologies as us. It is not difficult to just verify the concepts of a framework, but when you apply these concepts to actual projects, all kinds of problems will come one after another, and all kinds of problems that cannot be found in official documents will follow. The first thing to do when learning new technologies is to subscribe to relevant technical community forums. No matter what problem you encounter, there will always be someone who has encountered it before you, and may have found a solution. P.S., you can also answer questions raised by others, and it feels so good. You can also subscribe to the "Happy Coder" programmer journal by email to get more programming knowledge.

5. Follow blogs and add your own comments

As I said in the previous point, we are not alone. Thousands of technology enthusiasts from all over the world publish their technical insights on blogs. On blogs, we can find many different views on the same technology. Some people may think it is a powerful technical feature, while others may think it is a stupid framework. So for the same technology, you will hear two different voices in the blog. If you see a good blog, you can write your own opinion and reply in the comments.

6. Read the source code of open source frameworks

Good developers always know how to use a framework. But if you want to be a good developer, then you need to study the source code of various successful and popular frameworks to understand its inner working mechanism and best practices. This is an efficient way to use a framework.

7. Understand the development trend of related technologies

In an open source environment, software development technology is always evolving. The so-called new framework now may become obsolete in time. Problems that cannot be solved on the current framework may no longer be a problem on the new framework. So we must always pay attention to the birth of new things and the demise of old things.

8. Keep frequently used code snippets/utilities on hand

Sometimes we may need to copy-paste/write the same code snippets/configurations over and over again. So, it is good to save some configuration snippets like log4.properties, jdbc configuration, and utilities like StringUtils, ReflectionUtils, DBUtils. These things themselves may not make you stand out, but think about it, if your co-developer wants you to help him get a list of property values ​​from a collection of objects, and you can solve it in a few minutes with just ReflectionUtil, you will stand out all of a sudden.

9. Understand different development methodologies

Be familiar with different development methodologies, such as Agile, SCRUM, XP, Waterfall, etc. Nowadays, the choice of development methodology is determined by the client. Some clients prefer Agile, while others prefer the Waterfall model. So being familiar with various methodologies is definitely impressive.

10. Document/blog your thoughts on technology

In our daily work, we may learn new things, new ways of doing things, new forms of practice and new architectural concepts. You can record these ideas in documents or blogs and share them with others. Because the solution you are solving now may be the problem that another developer in another corner of the world is "looking for and searching for", and your sharing will be no less than a long-awaited rain.
