How to become a Java developer? / What are the prerequisites to become a Java developer?
No need to follow a course at MIT to become a Java developer, many levels II courses exist. They are accessible to young graduates, non-graduates, or employees with a baccalaureate level. An example of Java training is that provided by the java school as part of its partnership with DTA Engineering.
Learning Java development is based on different stages:
In the imperative approach (1 day); we see the syntax of the language and the handling of elementary information, The object-oriented programming approach (4 days) where you learn how to manipulate information by block. The concepts covered: inheritance, polymorphism, encapsulation, interfaces.
The specifics of Java 8 (2 days), namely what does this new version bring? The acceleration of languages makes us think about the version to favor in learning (currently Java 11), but we prefer to favor the version used mainly in business. The program can thus evolve according to the languages, but especially the needs of the companies.
Good coding practices and unit tests (2 days); very important topics in business, Data persistence with JDBC and JPA (3 days),
Preparation for Java certification (2 days); only 60% of students obtain it because it requires cramming worthy of the highway code! For those who obtain it, it can reassure a company on the hiring of a beginner or demonstrates a passion among certain candidates.
Java EE (2 days); the objective is to know the mechanisms that allow exchanges with the front (TOMCAT server, JSP) to know how to architect the applications and be able to intervene on the oldest ones, Learning the master of frameworks, namely Spring, to allow the development of web applications (7 days).
Finally, 10 days are devoted to implementing the acquired skills in agile mode through an end of training project presented to everyone!
Are additional skills required to be a good Java developer?
Of course, to be a good Full Stack Java Developer, the learning doesn’t stop there; 12-day training on the front line (HTML, CSS, bootstrap, angular, etc.) is included, as well as on the necessary tools, agility, interpersonal skills, etc.
