Java is a programming language that is used to develop various kinds of software applications such as web applications, mobile applications, desktop applications as well as enterprise applications. Java developers are in high demand all over the world. If you are interested to become a full-stack Java developer, you should first understand the skills needed to make a successful career in this field.

A full-stack Java developer is a web programmer who uses Java, a popular computer programming language to develop both the front-end as well as the back-end of a web application. Apart from designing, developing, and maintaining web applications, these professionals are also responsible for creating and integrating APIs and managing the database of applications.Java full-stack developers are skilled in Java-based frameworks, tools and libraries involved in both client-side as well as server-side development.

Java full-stack developers use code in all the layers of web-based applications comprising the front-end, back-end and the database layer. Elements that appear when users interact with an application are designed in front-end development, while the data that supports the visible elements of the application is the back-end development. The database layer basically works as storage which is used by the application to recall data within the other layers. Java full-stack developers’ main goals are implementing features in an application that provide a seamless user experience, optimizing application performance, and ensuring security of application. 

Full-stack Java developers create web-based applications either for a company or work as a consultant for businesses. They often lead web-development teams for designing new websites and updating existing websites. Here are some basic steps you can follow to become a full-stack Java developer:

The first step towards becoming a full-stack Java developer is to learn the basics of Java. It is a complex programming language that may take some time to master. You can start by reading books on Java or practicing coding by watching instructional videos. You can also enroll yourself in online courses for a more professional learning experience.

To further develop your skills in coding, enroll yourself in a course, be it online or classroom. Most degrees in computer science and web design will have Java, front-end and back-end development as a part of their syllabus. This can help you get a job as a full-stack developer as after completion of the course in the relevant field, you would be familiar with advanced coding techniques as well.

You can start by seeking apprenticeships and get additional training by working with an expert in coding. You can also apply for internships or try for entry-level positions to gain some on-the-job experience. In this way you can work on improving your coding skills and further apply for full-stack Java developer positions.

Before you enter the field as a full-stack java developer, you will have to craft your resume accordingly. Highlight your knowledge on the subject, the courses you have done or any additional skill or experience you have on the subject. Ensure to express your confidence to work independently on projects as well as a team.

Let’s look at some of the skills needed to become a full-stack Java developer:

To become a full-stack Java developer, one of the important skills is having the knowledge and understanding of front-end development including technologies such as CSS, HTML, and JavaScript. Front-end framework knowledge involves the capability of creating design elements and combining them with coding to display an user interface in web applications, that is responsive and effective.Some of the front-end frameworks used by full-stack developers are React and Angular.

Learning back-end development is also important for a full-stack developer once he is an expert in front-end frameworks. It requires learning how to use frameworks such as Hibernate or Spring to create scalable and robust applications.

Integration of microservices is one of the skills that may come in handy as they serve as the functional components of a program that uses service-oriented architecture. You can learn the Spring Framework as its functionality relates to development of microservices and can help employers see your skill in using the same.

Testing is a key skills for java developers. They are required to evaluate portions of code to check their usability in a program. During full-stack programming projects, developers create various unit and integration tests. Integration tests involve evaluating the performance of code when combined together. It is significant to know usage of unit testing frameworks like JUnit or Mokito.

Full-stack development requires usage of a lot of tools. Developers use them to collaborate, debug and test codes, etc. These tools help them in the automation of deployment of applications and aid in improving their efficiency. Some of the popular DevOps tools include Ansible, AWS and Docker. Other useful ones are NetBeams, Eclipse that help in integrated development environment.

Developers use Application Programming Interfaces (APIs) to integrate code into applications. As a full-stack Java developer, you must have complete knowledge on libraries and a thorough understanding of the process of creating APIs.

Apart from these technical skills, full-stack Java developers should have some practical experience in building small projects that they can apply to more complex ones. Participating in coding competitions and hackathons also help in showcasing your skills as well as learn something from other developers as well. Most Java developers have to work with large collaborative teams and therefore it is important to have the ability to perform as a team worker as well as manage large teams.

Java is an ever-evolving language with new frameworks and technologies being developed each day. You should always strive to keep learning and staying updated with the latest trends in Java, to stay relevant in this field throughout your career. So to become a full-stack Java developer, you must not only have technical knowledge but also some practical experience as well, along with the willingness to learn!
