This article mainly explains "how to become an outstanding Java programmer," interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's learn how to be a great Java programmer!

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

For Java programmers, a deep understanding of the concept of Object Oriented Programming is essential. Without a solid foundation in OOPS, you can't appreciate the beauty of object-oriented programming languages like Java. Learning the definitions of OO principles is not enough; the key is learning how to apply these principles to designing solutions in an OO way. Therefore, we should have a good understanding of object modeling, inheritance, polymorphism, and design patterns.

2. Mastering the core API

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

3. Continuous coding

Lu You once said,"The paper comes from the end and feels shallow. I know that this matter should be practiced." It's easy to come up with a solution in theory, but it's hard to realize how difficult the problem is until it's actually implemented. At this point, you will understand the language constraints that exist in the coding process, and thus design a *** practical solution. Therefore, do not interrupt coding.

4. Subscribe to Community Forums

We are not alone. A lot of people are working on the same technology as we are. It's not hard to just validate a framework concept, but when you apply those concepts to actual projects, all kinds of problems arise that can't be solved in official documentation. The first thing to do to learn a new technology is subscribe to the relevant technology community forums. No matter what problem you have, someone else has had it before you and may have found a solution. Ps can also answer questions raised by others, and it doesn't feel too good. You can also subscribe to Happy Coder Programmer's Journal for more programming knowledge by clicking Subscribe.

5. Follow the blog and add your own comments.

As I said earlier, we are not alone. Thousands of tech enthusiasts from around the world post their tech insights on blogs. On blogs we can find many different views of the same technology. Some people may think this is a powerful technical feature, while others may think this is a stupid framework, and everyone has their own views. So you'll hear two different voices on the blog about the same technology. See good blog can write their own point of view reply in the comments.

6. Read the source code for open source frameworks

Good developers always know how to use frameworks. 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 internal working mechanism and *** practice form. This is an efficient way to use frameworks.

7. Understand trends in related technologies

In an open source environment, software development techniques are constantly evolving. The so-called new framework now may become outdated in time. Problems that cannot be solved in the current framework may no longer be problems in the new framework. Keep an eye on the birth of new things and the death of old ones.

8. Have common code snippets/utilities at hand

Sometimes we may need to copy and paste/write the same code snippets/configurations over and over again. So it's good to save pieces of configuration like log4.properties, jdbc configuration, and utilities like StringUtils, ReflectionUtils, DBUtils. These things may not make you stand out on their own, but think about how your co-developer wants you to help him get a list of attribute values from an object collection that you can solve in minutes with ReflectionUtil.

9. Learn about different development methods

Familiar with different development methods such as Agile, SCRUM, XP, Waterfall, etc. The choice of development method is now up to the customer. Some customers prefer Agile, while others prefer Waterfall models. So it's really impressive to be able to dabble in all kinds of methods.

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 ideas of architecture. These ideas can be shared in a document or blog. Because the solution you're solving right now may be another developer's "search and seek" problem in another corner of the world, your share will be nothing less than a long drought.

At this point, I believe that everyone has a deeper understanding of "how to become an outstanding Java programmer," so let's actually do it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
