WA1865 Writing Java in O-O fashion Workshop Training and Courseware
(Coming Soon)
|
Learn how to write Java code to take advantage of four OO programming best practices. The four best practices of OO are Abstraction, Encapsulation, Modularity and Hierarchy. |
|
Topics
- Object-oriented concepts
- Identifying classes
- Object interaction, relationships and behavior
What you will learn
After completing this course, the student should be able to:
- Develop Java applications in accordance with the OO best practices
Audience
This course is intended for anyone involved in the development or design of Java based software.
Prerequisites
Familiarity with Java development is required.
Duration
Three days. |
