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.

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.

What's inside
Syllabus
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.

Reviews summary
Design patterns: oo design for effective code
Learners say this engaging course delivers lucid explanations about object-oriented design patterns and principles. Students largely appreciate the rich theoretical content, well-structured assignments, and diverse quizzes. While some wish for more practical examples and clarity in UML diagrams, the course is highly recommended for learners of all experience levels looking to improve their software development skills.
assignments help solidify understanding
"This is an excellent course for the individuals who are seeking to advance career in programming because design patterns are the flavor of programming and the code smells if it does not have patterns implemented."
"Assignments are good and the mechanism of peer review is very good."
"An awesome and thorough introduction to design patterns. The assignments helped very much with implementing them in a real world application."
course material is organized and well-paced
"Very nice application. It helps me understand more about the design pattern, which is essential for software developers. I highly recommended this course to software graduate, junior, middle software developers."
"Very well structured course. Assignments are good and the mechanism of peer review is very good."
"It's a very good course to take if you're specializing in software architecture or just formalizing your specialization."
appropriate for beginners and experienced learners
"I am just a junior programmer now, but after completing this course I can recommend it to other juniors."
"The course is good, but I think it can benefit of doing pure java exercises, rather than to have to depend on an application on android"
"I so glat to attend this cource and,
it was more interesting than I expected"
UML diagrams need improvement for clarity
"Overall a good course, but I found the UML diagrams very confusing."
"I was very pleased with the OO Design course of this same team, however, I am a bit disappointed with this course."
"The material is not well enough."
needs more real-world examples and exercises
"The course is good, but the review is a little slow. Maybe he number of people studying this course is small?"
"Content is good. Discussion forums are not useful. Course assignments are based on Android which adds an extra level of difficulty which is not necessary given the content, and do not demonstrate the value of any of the design patterns taught."
"I really enjoyed how the concepts are explored. My humble suggestion is to increase the level of examples in the code smells section."
