How to stand out as a Java Developer!

These specialized programmers work with other software engineers, web developers, and others to create software and applications using the Java programming language. Java is used to create websites, business applications, and other things.

They are active throughout a product or solution's entire development life cycle. They can recognize and evaluate any issues that arise, then come up with effective solutions. Employers are on the lookout for both junior and senior Java developers, depending on what is required.

Java has long been one of the most widely used programming languages. The number of specialists seeking Java proficiency is rising quickly. Being a good Java developer is no longer sufficient due to the intense competition; in order to stay ahead of the pack, you must also gain deep knowledge and become familiar with numerous concepts. This blog post can assist you in answering the question, "What should I learn to stand out as a Java developer?" if you're the one who's having trouble answering it.

8 Tips to become a better Java Developer:

1. Obtain a Firm Understanding of OOP Principles

Because Java is an object-oriented language, developers should strive to gain a thorough understanding of the OOP principles rather than underestimating them. Gain a thorough understanding of object modeling, SOLID principles, design patterns, inheritance, and other ideas while learning how to apply OOP principles to programming. When writing software, especially in a contemporary object-oriented language, keep these things in mind.

2. Learn the essential APIs

If you don't understand the basic language constructs and APIs, it doesn't matter how strong your theoretical knowledge is. The core Java APIs, such as java.lang.*, I/O, exceptions, collections, generics, threads, JDBC, etc., require very strong hands-on experience. No matter which framework you choose to use, it is imperative that you comprehend the ideas behind servlets and JSPs when it comes to developing web applications.

3. Learn about the Spring Framework.

Modern Java development is significantly influenced by the Spring framework. Companies frequently use Spring framework components, such as Spring MVC and Spring Boot, to create microservices or web applications. A local Java method can be transformed into a management operation or remote procedure by developers who are aware of all the benefits of the Spring framework.

Getting acquainted with fundamental Spring concepts, such as Dependency Injection (DI), Inversion of Control (IoC), and Spring MVC in general, is the first step if you have never used Spring before.

4.Continue coding.

When discussing things theoretically, they appear to be simpler. In theory, we can solve a problem very quickly. But as soon as we begin using our strategy, we will understand the scope of the issue. While coding, you will learn about language restrictions or design best practices. So continue writing code.

5. Find Out About the Most Important APIs and Libraries

If you want to differentiate yourself, you must be familiar with APIs and libraries because they sit alongside Java frameworks. They have the second-largest community on the StackOverflow Q&A website and are an essential component of the Java ecosystem.

I could write a dozen articles on this subject alone because it is so vast, but generally speaking, a highly skilled Java developer is someone who has a thorough understanding of the core APIs, primary and third-party libraries, and the Java Development Kit (JDK). In order to avoid any misunderstanding, I should clarify that the specialists are not required to be familiar with all possible APIs and Library components.

6. Become an expert in Java 11

The final iteration of Java 15 was recently released, which was witnessed by the Java developer community. However, when it comes to implementing new versions of anything, the Java domain's software development flow is typically quite slow. Enterprise projects are particularly fond of the adage "if it ain't broke, don't fix it."

In those projects, even the smallest adjustments must adhere to strict security standards, and older technologies are frequently employed. For instance, you are unlikely to encounter any technology that is less than five years old in a bank, airline, or insurance system. Here, older equates to reliable, secure, and stable.

7. Join discussion forums

We're not on our own. The technologies we are developing are being worked on by many other people. While using a framework for a straightforward proof of concept may not present you with many difficulties, when you begin using it for actual projects, you will run into strange problems for which there is no official documentation. The best and first step when working on new technology is to join relevant technology forums. It's possible that someone else in the world has already encountered your problem and found a solution. And it would be fantastic if you could respond to the queries posted by other forum users.

8. Read blogs and leave comments

Around the world, tens of thousands of fervent technology enthusiasts blog about their observations. Other blogs and developers' perspectives on the same technology can be very helpful. Some people might find certain features of a framework to be incredibly useful, while others might find those features stupid and pointless, each with his own justifications for feeling that way. You can therefore see both the positive and negative effects of other developers' use of those tools.

Responding to or leaving comments on posts with your thoughts and inquiries is another valuable way to benefit from reading other blogs.

Take away:

If you don't already know them, you can start with the more crucial things like learning Java 8 and the Spring Framework; however, if you are already proficient in those, you can move on to more advanced topics like unit testing, JVM internals, and DevOps.

Before moving on to the next tip, you need to choose one at first, such as Java 8, and commit to using it. Learning more about your IDE is a good option if you're looking for some low hanging fruit.

You are already familiar with your IDE, so taking the time to get to know it better will quickly increase your productivity and quality as a Java developer.
