Before we explore everything you need to know to become a Java developer, you’ll need to understand what Java is. Community driven content discussing all aspects of software how to become a java developer development from DevOps to design patterns. The
Oracle Technology Network License Agreement
for Oracle Java SE is substantially different from prior Oracle JDK 8 licenses.
We’ve seen in the past huge releases containing many, many things and the reason they get pushed out a year, six months, two years, is because largely we have been waiting for different features. So Java 8 was delayed because of lambdas, Java 9 was delayed because of Jigsaw. In fact, Java 8 largely was also delayed because of Jigsaw which was later pulled. So, everything else, all the other benefits in Java, you can’t get hold of. If you’re looking at something more modular, you could actually upgrade some modules without needing to upgrade the whole application at once. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the JavaTM platform.

Understanding program architecture is crucial, as it’ll inform how you develop new projects. As a Java developer, you work closely with your business’s development team. This means you will need to attend regular standups and meetings, help colleagues with problems, and help your team plan and manage your projects.
- These projects don’t have to be sophisticated or perfect, as they are simply a way for you to demonstrate that you can develop a range of applications with Java.
- The first reason is because everyone is getting a little bit fed up of Java slipping constantly.
- That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.
- This latest release improves the performance, stability, and security of Java application development.
- Helidon supports both MicroProfile and Reactive development styles.
You’ll also need excellent communication and problem-solving skills as Java developers solve technical issues with the rest of their business’s IT department. When designing your resume, make sure you include your new Java developer skills. These may consist of Java development skills, code testing skills, SQL knowledge, project management skills, vendor liaison skills, and OOP knowledge. Soft skills help people succeed at work and include communication, problem-solving, and teamwork skills. As developers must update programs to ensure they’re functional and secure, you need to develop regular updates. You will need to plan, design, test, deploy, and collect user feedback on the update to build efficiently.

Sometimes, even if you are not planning to do any Java development on a computer, you still need the JDK installed. For example, if you are deploying a web application with JSP, you are technically just running Java programs inside the application server. Because the application server will convert JSP into Java servlets and needs to use the JDK to compile the servlets.
Java is Everywhere
You should aim to create several Java applications for your portfolio (including at least one web application). These projects don’t have to be sophisticated or perfect, as they are simply a way for you to demonstrate that you can develop a range of applications with Java. If you are an experienced developer, you will need to understand your business’s programs, IT infrastructure, and program architecture in-depth.
