Course Description
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 6 platform can be used to develop applications using these libraries and features.
Target Student:
This training course is for experienced Java developers who need to be able to develop advanced applications using the Java programming language.
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.
Delivery Method: Instructor led, group-paced, classroom-delivery learning model with structured hands-on activities.
Performance-Based Objectives
At the end of this training course, students should be able to:
- 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
- Refactor Java 1.4 code to use the Enum types in Java 5
- Understand multithreading in Java
- Understand how concurrency works in the Java platform
- Use the various Java 5 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
