This course extends object-oriented analysis and design by incorporating design patterns to create interactive applications. Through a survey of established design patterns, you will gain a foundation for more complex software applications. Finally, you will identify problematic software designs by referencing a catalog of code smells. You will be challenged in the Capstone Project to redesign an existing Java-based Android application to implement a combination of design patterns. You will also critique a given Java codebase for code smells. After completing this course, you will be able to: • Demonstrate how to use design patterns to address user interface design issues. • Identify the most suitable design pattern to address a given application design problem. • Apply design principles (e.g., open-closed, dependency inversion, least knowledge). • Critique code by identifying and refactoring anti-patterns. • Apply the model-view-controller architectural pattern.

Syllabus - What you will learn from this course
Introduction to Design Patterns: Creational & Structural Patterns
Design patterns help to solve common design issues in object-oriented software. You will learn what they are and how they can be applied. In this module you will learn the creational and structural design patterns. You will continue to learn and practice expressing designs in UML, and code some of these patterns in Java.
Behavioural Design Patterns
You will continue learning useful design patterns and add them to your toolbox. In this module, you will learn the behavioural patterns. This will include communicating them in UML and coding them in Java!
Working with Design Patterns & Anti-patterns
You will learn a design pattern that is very useful for user interfaces: model-view-controller, or MVC. Then you will learn some principles underlying the design patterns, to create software that is flexible, reusable, and maintainable. Finally, you will learn some of the symptoms of bad design, which we call code smells or antipatterns.
Capstone Challenge
In the previous modules, you were introduced to a variety of design patterns, and applied two of these to the example Android code base. Now, in the final module of the course, you will identify and fix specific code smells in this code base. After completing these tasks, you will be ready to complete the final exam.

Top reviews from Design Patterns
I have never had a chance to study CS at the university so I am always looking for ways to improve my knowledge - to keep up with fellow programmers. And this course met my requirements perfectly. :)
The course is a really good introductory course for beginners to understand new concepts and for intermediates to refresh basic software design patterns and anti-patterns.
