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.
This course is part of the Software Design and Architecture Specialization

Week
1Introduction 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.

3Working 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.

4Capstone 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.
