Beginning Java

This course provides an introduction to the Java language.

You will be taught the language basics and syntax. We cover the important parts of the language and standard libraries. You will receive an introduction to object-oriented concepts: inheritance, polymorphism etc. We look at language constructs such as abstract classes, interfaces. We show ways to write Java according to modern best practices.
