Software engineers deserve applause for creating amazing websites, applications, operating systems or any other digital technology. Generally, software engineers learn how to code in a few programming languages before they start their careers. Java is one of the most essential programming languages that every software engineer must know to excel in their careers. Being a Java full-stack developer is only possible if the software engineer is proficient in front-end and back-end skills.

• You should be comfortable running applications on Windows, MacOS or Linux.
• For comparison, the average web developer earns between $60,000 – $75,000 a year.
• You don’t have to delve into “how the things work in there” too deep.
• Understanding program architecture is crucial, as it’ll inform how you develop new projects.
• For example, a unit test might check that a method in an application returns the expected result when given a certain input.

You can also use both the familiar imperative code and the non-blocking reactive style when developing applications for Quarkus. Spring Framework encourages writing clean code, which is easier to test and maintain by providing you with features like Dependency Injection and Inversion of Control. It also has a rich API for most of the day-to-day tasks, and that’s why every Java developer should learn the Spring framework. If you want to become a Java developer in 2023, I strongly recommend you to learn Spring Framework first. This is one of the most popular Java frameworks, and literally, almost every single Java application I have worked on in the last 5 years, uses this framework. The best thing about Java is that it has a vibrant ecosystem, which means there are a lot of frameworks and libraries for almost anything. Usually, I don’t suggest a Java developer learn a framework until he needs to use it in his project.
