A Java Developer is an Applications Developer who works with the Java programming language to design, test, and implement software. Despite the similarity in name, Java is not to be mistaken with JavaScript, which is a completely different computer language.

If you're a Java developer with a passion for technology, you may use these ten steps to help you become a better Java developer. In this article, we will discuss the steps to become a successful Java Developer.

Have a solid foundation in OO principles and a thorough grasp of them.
A thorough understanding of object-oriented programming is essential for a Java developer. You can't appreciate the beauty of an object-oriented programming language like Java unless you have a firm basis in OOPS. Even if you're using the OOP language, you could still be coding in a procedural manner if you don't understand what OOPS is. It won't assist much if you just study the OO concept definitions. We should be able to apply those concepts to the design of an OO solution. As a result, one should be well-versed in object modelling, inheritance, polymorphism, design ...
... patterns, and so on.

Understand the fundamental APIs
If you don't understand the language constructs and essential APIs, it doesn't matter how great your theoretical understanding is. In the case of Java, extensive hands-on familiarity with core APIs such as java.lang.*, I/O, exceptions, collections, generics, threads, JDBC, and so on is required. It's critical to understand principles around servlets and JSPs while developing online applications, regardless of which framework you choose.

Continue coding
When discussing things hypothetically, they appear to be simpler. In theory, we can easily provide a solution to a problem. However, once we begin implementing our strategy, we will be able to see the scope of the problem. While coding, you will learn about language restrictions and design best practices. So continue coding.

Forums that you can join
We're not on our own. There are several people working on the same technology as we are. While a small proof of concept on a framework may not provide any actual obstacles, when you use it on real applications, you will run into strange situations for which there is no answer in their official documentation. Subscribing to relevant technological forums is the greatest and first thing to do when starting to work on new technologies. Whatever problem you're dealing with, someone else somewhere in the world may have already dealt with it and discovered a solution. Also, it would be fantastic if you could respond to questions posed by other forum users.

Read and react to blogs:

You are not alone, as I already stated. Thousands of enthusiastic technology nerds write their thoughts on technology all over the world. Other blogs and developers can also provide helpful insights on the same technology. Some people may think some framework elements to be quite beneficial, while others may view them to be foolish and meaningless, each with his own reasons for feeling this way. As a result, you can see both the positive and negative feedback from other developers who have used such products.

Another method to get anything out of reading other blogs is to respond/comment on them with your thoughts and questions.

Examine the source code of open-source frameworks

A good programmer will be able to use a framework. However, if you want to be a great developer, you should examine the source code of several successful, well-known frameworks, where you may see the framework's internal functioning mechanism as well as best practices. It will be really beneficial when employing frameworks in a more efficient manner.

Be aware of new technological developments.

When it comes to open-source software development trends, they are exploding. By the time you have a decent understanding of how to utilise a framework, it is likely to become obsolete when a new framework with a super-set of features enters the picture. The problem you're trying to solve with your current framework might be solved more easily with a single line of settings in the new framework. So keep an eye on what's coming in and what's leaving the image.

Keep a list of frequently used code snippets and utilities on hand.

You may find yourself writing/copy-pasting the same code/configuration over and over again. It will be more useful to save configuration snippets like log4.properties, JDBC configuration, and utilities like StringUtils, ReflectionUtils, and DBUtils. I understand that it won't make you a great developer on your own. But assume if a co-developer asks you for assistance in retrieving the list of values for a property from a collection of objects, and you simply used your ReflectionUtil and provided the solution in a matter of minutes: That will set you apart.

Be familiar with various development approaches

Be familiar with a variety of techniques, such as Agile, SCRUM, XP, and Waterfall. Nowadays, the client determines the development technique. Some clients prefer Agile, while others prefer the Waterfall style. As a result, having a basic understanding of diverse approaches would be extremely beneficial.

Keep track of your technological thoughts in a journal or on a blog.

You may discover new and better ways of doing things on the job, as well as best practices, architectural concepts, and so on. Continue to write down your views, blog about them, and/or share them with the rest of the community. Assume you addressed a strange problem that arose while performing a small POC and blogged about it. Perhaps other developers around the world are experiencing the same problem with a production-ready application. Consider the value of that solution to that developer. So, write down your thoughts; they might come in useful for others or for you one day!
