Java Design Patterns
Description
In this course, programmers will be introduced to ideas and techniques commonly referred to as Java language patterns. Patterns are reusable solutions to recurring problems arising during software development. This course will introduce the programmer to common patterns and their implementation in the Java language. Patterns will be associated with their uses within the Java API, followed by design and implementation exercises to correlate several design patterns.
To make the best from the course, the first day will be devoted to some java language core issues such as reflection and memory management. The course starts with a “Pitfalls” section in which we will discuss some common misunderstandings in the Java language, clarify them and learn how to avoid them.
Intended audience
This course is intended for Java programmers, Java designers and Object Oriented analysts that need to design system-level, software-level or module-level components to be implemented in the Java programming language.
