Test author : Pierre Bihannic

What better way than a student in a computer school to understand the needs of a junior who is starting out in Java?
We contacted the MIAGE of Sophia Antipolis to carry out this test. It was Pierre who volunteered for the exercise. Graduated from a DUT specializing in computer science and currently in computer science license 3, Pierre has devised a test to test your basic knowledge of JAVA.
For recruiters who go through it, Pierre has been passionate about IT since his early childhood. He seeks to specialize in software or web development.
You can find Pierre on WeLoveDevs and on Linkedin !
