Course Description
Overview
This Advanced Java Programming course is designed to provide students with advanced training in developing software using the Java Platform, Standard Edition, or Java SE. It is intended for students with solid experience in structured and object-oriented Java programming, including use of the Collections API and exception handling. Generic types should be understood, at least at a basic level; the course does begin with a refresher and then a more advanced treatment of generic types.After a quick introduction to the Java Time API, students get familiar with the I/O streams model, file handling, and object serialization, and learn to use streams to communicate over network sockets. A two-chapter unit covers multi-threaded programming and concurrency techniques. We look at dynamic typing in Java, in the Reflection API and with dynamic proxies, and understand the underpinnings of source-code annotations.
Objectives
Upon completion of the Advanced Java Programming course, students will be able to:
- Make effective use of Java generic types.
- Understand the structure of streams in Java, and learn how to use streams to manage file I/O.
- Learn how to use Java Serialization to internalize and externalize potentially complex graphs of objects.
- Communicate between processes using network sockets.
- Write multi-threaded Java applications that safely manage concurrent access to application state.
- Use the Reflection API and dynamic proxies for highly generic tasks, discovery, or code-generation.
- Use standard annotations and develop custom annotations to express meta-data in Java source files.
- Build unit tests for Java classes using JUnit.
- Write effective tests, and design classes for testability.
- Understand test-driven development (TDD) and use dynamic mocking to support isolated testing.
Audience
- Experienced Java programmers
Prerequisites
- Solid Java programming experience is essential -- especially object-oriented use of the language. Language features and techniques that are integral to some lab exercises include interfaces and abstract classes, threading, generics and collections, and recursive methods
