Become a Java Development Expert

Craft enterprise-ready back-end services with the language that powers banks, airlines and billions of devices. Our 12-week module begins with core Java syntax and unit-testing katas, then layers on OOP design patterns and powerful collection APIs. You’ll wire Spring Boot to expose REST endpoints, secure them with JWT and break monoliths into dock microservices that deploy through CI pipelines. Clean-code practices, Maven/Gradle builds and Testcontainers integration tests keep commits production-grade, while peer reviews sharpen system-design storytelling. A final capstone showcases your microservice suite and positions you for Junior Java Developer roles and beyond.

Our Bootcamp is THE IT training for Java developers - both for career changers and experienced professionals. Anyone who is motivated enough to learn something new, who is interested in IT and who wants a change in their job can become a Java developer. Career changers and lateral career advancers will be right at home at this bootcamp. For learning Java, you should ideally already have some previous knowledge of programming - we will be happy to explain the details to you in an introductory call.

Learning to program in Java makes more sense than ever! German companies are desperately looking for well-trained specialists. Large companies in particular are increasingly digitizing themselves and are relying on the Java programming language developed by Oracle. A university degree or a correspondence course in computer science or business informatics is no longer the only ticket: HR managers of large corporations, as well as small start-ups, are looking for team-oriented, motivated and adaptive practitioners who can get started in a team without much training - and our bootcamp graduates answer all of the above.

Absolutely! Many individuals have successfully transitioned into Java development through bootcamps, even without a prior tech background. These programs are designed to take you from the basics to a job-ready level within a few months. For instance, the Java Bootcamp offers a 12-week intensive course that covers object-oriented programming, backend and frontend technologies, and hands-on projects.

Key factors for success include:

Commitment: Dedicate time daily to grasp new concepts.
Practice:Regular coding exercises to reinforce learning.
Support:Utilize mentorship and peer support available during the bootcamp.

Upon completion, graduates often secure roles such as Junior Java Developer or Full Stack Developer, with starting salaries ranging from €45,000 to €55,000 annually in Deustchland.
