Course Overview


Modern Java code extends well beyond object orientation and the associated principles. This hands-on course, delivered using Java 11, endeavours to provide a grounding in advanced topics including generics, functional programming, concurrency, annotations, reflection and security (among others).

This course assumes you are familiar with the fundamentals of the Java language including object oriented principles and that you can build simple applications. If not you should consider our Java Programming 1 / Java Developer course instead.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

Company Events

These events can be delivered exclusively for your company at our locations or yours, specifically for your delegates and your needs. The Company Events can be tailored or standard course deliveries.

Course Schedule


Target Audience


The Java Programming 2 / Java Advanced Developer course is aimed at existing Java developers who are seeking to build on their knowledge of the fundamentals so as to make full use of the language’s advanced features.

Course Objectives

After you complete this course you will be able to:

Build and/or maintain Java applications that exploit advanced features. It also serves as good preparation for developers seeking to contribute to enterprise level applications built with Java EE/Jakarta EE/Spring or similar.
