Java Basics

Accueil » Formations » Java » Java Basics

This course is an entry point for anyone who wants to move into Java development. Java is both a programming language and an execution platform.
It is the foundation for the development of applications based on Java EE technology (WebSphere, WebLogic, JBoss, Tomcat,...).
Our training focuses on the object approach: understanding its founding principles and putting them into practice with Java.
We believe that an object developer develops faster because he codes less (and better).
The Java platform offers a large number of APIs that we could not reasonably cover in five days. We decided to present the APIs needed to use a database: JDBC, a tool that will certainly be essential to write a first management application.
On request, we can adapt this training to use another IDE than Eclipse in the practical works: Oracle NetBeans, IntelliJ IDEA, IBM RAD ...
