Programming languages are deigned to shape out future, they are used to make those apps, beautiful websites, and software products you see today. There are so many programming languages that programmers and developers can use today from C language to C++ to Python and others. Java is a language that is considered versatile because of its ability to be used in designing customized apps that are fast and light.
In 2019, TIOBE Index ranked Java as the top programming language, sending a statement to developers, programmers, and app or website owners that they need to think of Java as a mainstream language. Java is used by many companies - large or small. Think of the giants like Amazon, Google, and the rest, they use Java. Becoming seasoned Java developers puts individuals in the frontline within the industry since many companies are looking for developers well-versed with Java. Now that you know how Java is trending, what are some of the things people can do to be successful Java developers in 2020?
1. Learn and Master Core Java SE
If you want to succeed as a Java developer, you will need to start with Java SE and make sure that you master it. Ensure that you grasp basic concepts such as operators, arrays, loops and others. Besides, learn the general-purpose API's such as java.math, java.oi, or java.lang and many more. Have an understanding of these API's. In Java, you will encounter OOP's concepts, so you need to begin learning them as well.
2. Continue Practicing Java
Once you have started Core Java, you can't stop, you just have to continue practicing the language. With more practice, it helps you write syntax without making basic errors. In theory, you may be able to offer a solution about Java, however, when it comes to implementing or showing it out in Java language, it becomes a tall order. When you practice Java, it helps you understand the limitations of the language as well as the best design practices you can employ. Your success in using and implementing Java is to keep coding and doing everything Java - try making mini Java projects in any kind of topic you have learned. That way, you will be on the road to being a Java pro. Soon you will find that companies seeking to hire Java developer are eyeing for your skill and experience.
3. Get to Learn Java EE
When you’re done with Core Java, move on to Java Enterprise Edition or Java EE. This edition is known as Advanced Java as the name “enterprise” suggests. Learning Java EE allows you to work on projects like web development because Java EE comprises specifications of extra features such as web services and distributed computing. For example, there are technologies like Java Server Faces, WebSocket, Servlet, and others, which are designed for web specifications.
4. Consider Making Projects Using JSP and Servlets
5. Move on to Hibernate Framework and Spring Framework
After you are finished with SE and EE, you can now consider learning Java Frameworks including Spring Framework and Hibernate Framework. In Java, Spring and Hibernate are the most famous and most Java development companies develop web apps using Spring frameworks like Spring MVC, Spring Boot, and Spring Cloud. When it comes to Hibernate framework, you find that it is commonly used to map domain object-oriented models to relational database. If you are familiar with these frameworks and you've practiced them properly by doing projects, then you stand a better chance of finding yourself working in a Java development company as a developer or programmer.
6. Learn More on DevOps - Jenkins and Docker
Not only will Java programmers learn Java and its frameworks, they also need to learn others things like DevOps. Many developer companies are shifting to DevOps and making use of continuous integration as well as deployment. There are so many tools and principles to learn in DevOps, and this is what overwhelms a majority of developers. When you learn DevOps, it shows that you are a dedicated programmer that knows how to manage the environment. If you can manage, automate, and improve the entire development structure then you are likely to become a DevOps engineer.
7. Learn Git
If you are a programmer, you know about Git or Github. These have been around for a while and because many companies are now moving to Git, a Java programmer will need to learn Git. Many programmers have not mastered Git probably because when they were becoming programmers they did not need it because the code was in CVS or SVN. However, with the changing game where SVN and CVS projects are now migrating to Git, it is time to master it.
8. Join Java Forums and Discuss Groups
As developer, try reading documentations as well as open-source frameworks source-code so that you keep yourself well-informed of the latest Java technologies. You can even subscribe to a Java oriented newsletter to see, which Java technologies are being released and start learning them. Follow blogs and Java programming social platforms such as StackOverflow, java-forums, and dreamincode forum or coderanch forum. These resources will help you build your Java programming and coding knowledge.
In a nutshell, these are some of the things you want to focus on if you look forward to be among the most successful Java programmers in 2020. The programmer and developer business is evolving, things are changing fast and as the professionals in the industry, you have to ensure you are not outpaced by the technology changes. Whether it is about Spring Framework, Unit Testing , Spring Boot, Android, or RESTful Web Service, you really need to learn these things. They will count in your success as a Java developer.
