Javaprogrammering – Avancerad
This course is for those who want to go further and learn advanced Java programming! You will learn how to apply proven Design Patterns, various techniques for managing XML files, both for configuration and for data storage. You will learn how to write advanced multi-threaded applications using both traditional thread classes and the Executor Framework.
You will understand the underlying technology of network programming and how to build distributed RMI applications. You will learn how to create reusable components; JavaBeans. Finally, the course includes methods for analysis of existing classes, optimization of existing code and performance measurement for Java applications.
Exercises
