Java Programming Advanced: Mastering Modern Language Features

Deepen your Java knowledge and take a head start.

Description

Do you already know the standard features of Java, but do you want to know what else the language and platform have to offer? Then this course is for you!

A new Java version is released every six months, containing new language features, tools, and APIs. Unfortunately, backward compatibility with older versions is no longer guaranteed. Therefore it is essential to keep up so you can always use the latest features while keeping the steps to upgrade small.

In this course, you will learn features that only some know but are crucial for an experienced developer. We assume the latest Java version. We also look at future developments. In this way, you deepen your knowledge and take a head start on the average Java developer.

It is a practical course in which theory and assignments alternate.
