Course description
Modern Java code extends well beyond object orientation and the associated principles. This hands-on course, delivered using Java 17, 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.
Who will the Course Benefit?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 ObjectivesThis course aims to provide the delegate with the skills needed 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.
Upcoming start dates
Suitability - Who should attend?
Delegates attending this course should be familiar with the fundamentals of the Java language including object oriented principles, and should be able to build simple applications. This knowledge can be obtained by attendance on the pre-requisite Java Programming 1 / Java Developer course.

Well thought out course. Enjoyed that the requirements/parts for the Exam activity developed as I was taught new concepts. All concepts on the course were explained well as were...
Best lecturer I've ever had. Brilliant paced and brilliantly presented. Hope future training courses have Stuart as a lecturer.
