Java Fundamentals

Procedural programming language (like C, PHP, Basic, Pascal) or object oriented programming language knowledge required.

The course covers the basics of Java development.

It introduces students to Java technology and teaches them basic Java syntax and concepts, leading to the creation of a simple program. Training goes through the essential concepts and features of the Java Programming Language, focusing on exceptions, basic input/output, concurrency, regular expressions, Java collections framework and the platform environment. The course finishes when all basic Java features have been explained and trained.
