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.

TOP REVIEWS FROM DESIGN PATTERNS

by AAMay 25, 2020

The demo could have been also possible with any simple IDE, as installing and configuring Android Studio could be irrelevant for some students.

by AMMay 8, 2020

i learned a lot form this great course thinks for every one who contribute for such a course and i hope i finish the rest of it's specialization

by XJJan 30, 2018

Tying the assignments to an Android Studio project was overkill; the same principles could have been demonstrated with a SIMPLE java application.

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.

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.
