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.

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.

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

by EWJul 20, 2022

Good overall. Some of the discussion links go to expired discussion-groups. And a link to a quick summary of each of the patterns would help.

by RJMar 17, 2022

The course and the instructor was so good. The curriculum was well designed and of appropriate length. I really enjoyed and learnt skills that I would be able to apply while developing real software

by ZPSep 17, 2019

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. :)

by OBMay 24, 2020

Very rich content. However, i don't think the community reviewing system for assignments

is the best, if there is a more controlled reviewing option can be used, i think it will be better.

Frequently Asked Questions

When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
