Advanced Java Programming

3 days practical workshop for up to 12 people.

This advanced training course is for experienced Java developers who need to go into more depth into the core features of the language that are not typically covered on basic Java programming courses. The course details subjects that get cursory coverage in most books and courses, like generics, multithreading, socket programming, synchronization, and annotation development and looks at how the Java 8 platform can be used to develop applications using these libraries and features.

Layout

This training course combines lectures with practical exercises that help the delegates to put what they have learned on the training course into practice. The exercises specifically build on what has been recently taught and are built up as the training course progresses.

Training Course Objectives

Understand and work with generic types and collections
Understand the wild card and bounded features within generics
Read and write inner classes and understand where they should be applied
Understand multithreading in Java
Understand how concurrency works in the Java platform
Use the various Java threading libraries to implement robust multithreaded applications
Understand the structure of a class file
Use the reflection API to interact with a class file
Create and use Java annotations
Create single threaded and multithreaded servers using sockets
Create server client applications using sockets

Who it is for

This training course is for experienced Java developers who need to be able to develop advanced applications using the Java programming language.

Training Course Prerequisites

The training course assumes that delegates are already Java programmers.
It assumes knowledge of the object-oriented paradigm as object oriented theory is not covered in the content of the training course.
