This course takes Java beginners to the next level by covering object-oriented analysis and design. You will discover how to create modular, flexible, and reusable software, by applying object-oriented design principles and guidelines. And, you will be able to communicate these designs in a visual notation known as Unified Modelling Language (UML).
You will be challenged in the Capstone Project to apply your knowledge of object-oriented design by evolving and documenting the Java codebase for an Android application with corresponding UML documentation.

After completing this course, you will be able to: 
• Apply the Class Responsibility Collaborator (CRC) technique to analyze and design the object-oriented model for a problem.	
• Explain and apply object-oriented modeling principles and their purpose (e.g., abstraction, encapsulation, decomposition, generalization).
• Explain and apply different types of inheritance
• Explain the difference between association, aggregation, and composition dependencies.
• Express object-oriented models as Unified Modeling Language (UML) class diagrams.
• Translate between UML class diagrams and equivalent Java code.
• Apply design guidelines for modularity, separation of concerns, information hiding, and conceptual integrity to create a flexible, reusable, maintainable design.
• Explain the tradeoff between cohesion and coupling.

Object-Oriented Analysis and Design

Good software design begins before coding. After establishing the initial software requirements, design practices involve two main activities: conceptual design and technical design. In this module, you will realize the importance of design and object-oriented thinking, and learn how to design software using techniques like CRC cards.

Object-Oriented Modeling

Best software design practices have evolved alongside programming languages. Today, all developers should be familiar with abstraction, encapsulation, decomposition, and generalization, which are fundamental principles in object-oriented design. You will learn all of these principles and how they are expressed in Java and communicated visually in Unified Modelling Language.

Design Principles

Additional design principles will help you to create code that is flexible, reusable, and maintainable. In this module you will learn about coupling and cohesion, separation of concerns, information hiding, and conceptual integrity. You will also learn to avoid common pitfalls with inheritance, and ways to express software behavior in UML.

Capstone Challenge

In the previous modules you were introduced to object-oriented analysis and design, object-oriented modeling, and design principles. To cement your understanding of this material, you created a UML class diagram from an example Android code base, and used your understanding of the code base to make sequence and state diagrams to model its behavior. Now, in the final module of the course, given a description of new functionality and an updated UML class diagram, you will implement the updated design into the Android code base. After completing this development task, you will be ready to complete the final exam.

TOP REVIEWS FROM OBJECT-ORIENTED DESIGN

by VKFeb 27, 2019

Overall, a good course. The only drawback is that your assignments are being checked by students, who often have no clue what they are grading.

by APJun 30, 2022

Using Java and UML to start of with Design is a nice concept even though not heard in many Interviews but this course forms the foundations for Developers

by ARMay 20, 2021

Me ayudó a fortalecer los temas de Diseño Orientado a Objetos. Muy bien explicadas, sobre todo con la práctica, eso te ayuda a comprender mejor.

by NNFeb 20, 2019

The course covers the fundamentals of object-oriented design in a clear and systematic way. The homework assignments are defined clearly. The quiz sometimes feels a little overly simplistic.

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.
