Exploring Design Patterns From Modulus Training
Sponsored links
The course covers the patterns in the three core areas of Creational, Structural, and Behavioral and is hands-on with design projects and programming labs.
Objectives
Audience: Application developers, programmers, system designers, and project manager developers who need to improve the systems development through the use of design patterns.
Prerequisites
Some experience in object-oriented thinking/programming, professional experience with object-oriented technologies and UML diagrams, and a basic knowledge of Java.
