How to Become a Skilled Java Developer

Java is a popular and well-known technology in the IT industry, so it is not surprising to see many large applications in the enterprise, especially in the finance-related field or the largest transaction system where they have chosen Java.

So it makes financial sense to pursue a Java-related job as a software developer.

Learning about Java Virtual Machine

One of the most widely used Java programming languages ​​in the world, Java has a long history of development. 


  • Therefore, the best way to read and understand relevant technical texts is to have a general understanding of the Java ecosystem.

  • After you have a solid understanding of the JVM, you will have the fundamental knowledge you need to build more powerful and effective Java applications.


In addition, you should know which Java applications need to be re-evaluated, which objects are using more resources, what is the performance bottleneck, or, for example, which objects are using more memory or CPU.


Develop Spring Framework

Java developers learning the Spring framework is very important and essential because today many businesses prefer to use Spring frameworks like Spring MVC, Spring Cloud, or Spring Boot.

  • In addition to being ideal for building web applications and REST APIs, the Spring framework encourages dependency injection best practices.

  • If you are a new Java developer, you should watch and master some Spring and Java lessons to understand the basics of the framework.

Java API and Library

           If you want to know examples of good java programming, you should look at Java libraries. There are many helpful ways to write code in the core of Java. 

These libraries contain various information.

  • Java uses more than 20 different types of libraries and APIs. 

  • Familiarizing yourself with this writing style will greatly enhance your coding skills.

Develop Microservices

          The architecture of Java software continues to change as many companies move from large applications to microservices.

  • Learn about the microservices architecture and if you are interested as a Java developer, then create microservices in Java.

  • Spring Cloud and Spring Boot are the most popular frameworks because they simplify microservices in Java.

  • Master Microservices with Spring Boot and Spring Cloud Course Work as a Java developer without reading books and surfing the web.

Develop the Design Pattern

              The design pattern is used by most of our frameworks. This makes the framework more adaptable and scalable without breaking the code over, and over again. 

  • Design methodology can help our ability to create code effectively and efficiently. 

  • There are already more than 25 different design patterns for creating, structuring, and behaving objects. 

  • Each pattern serves a specific role in making it easier to improve functionality in the future without tearing all the existing code and starting from scratch.

Develop Dev Tools

One of the most important characteristics of the best Java developers is to be very proficient with their tools. 

  • In addition to knowing more about tools than the average developer, they also understand their tools better.

  • IDEs like Eclipse, NetBeans, and IntelliJ IDEA are important tools for a Java programmer, so it makes sense to invest some time in developing your knowledge.

                Since you use them more often than you realize, even a few simple suggestions can make a big difference. Eclipse Debugging Techniques And Tricks on Udemy is a great course to brush up on your knowledge of Eclipse while taking your IDE skills to the next level if you're serious about using Eclipse.

Develop DevOps

          DevOps knowledge is essential for the modern Java developer. He should be familiar with Continuous Integration and Continuous Deployment and how Jenkins helps in these processes.

  • This becomes even more important for senior Java developers who are often responsible for establishing coding best practices and creating environments, scripts, and guidelines.

  • Learning DevOps to CI/CD with Jenkins Using Pipelines and Docker on Udemy is a great course if you need some resources. 

  • You will get in-depth knowledge of Maven and Jenkins, not just CI and CD.

Develop Scala or Kotlin

                     Because of how much that experience has helped me, I strongly advise Java developers to choose a new JVM language.

  • It will not only increase your productivity but also help you to enter the Android development field. 

  • If you want to learn Kotlin and need a good resource, the Complete Android Kotlin Developer Course is a good place to start.

Develop the Unit Testing

       As a Java developer, testing is an important skill, especially unit, integration, and automation testing.

  • Java developers have a variety of tools for unit testing, integration testing, and automated testing, and testing has advanced significantly.

  • You can invest a lot of time in improving your testing skills in Java, but for those new to Java and unit testing, JUnit is the best library. 

  • Every Java developer should know how powerful and adaptable JUnit 5 is, the latest version.
