This is similar to how objects will interact to complete a given task. All of those interactions between the different people were needed. A sequence diagram describes how objects in your system interact to complete a specific task. Knowing how to break down a system into classes is essential in creating meaningful sequence diagrams. Now, let's go into more detail, because a sequence diagram is another type of UML diagram, to fully understand it, you should have a good grasp of objects and basic UML class diagrams. And the cashier will give it to the person. The shuffle cook the burger, give it to the cashier.

The cashier will then talk to the chef of the back to tell him my order. That person will go to a restaurant and talk to the cashier and order a burger. Let's say that a person wants to order a burger at a local fast food restaurant, here is a simple sequence diagram of the scenario. Simply put, think of a sequence diagram like a map of conversations between different people, where this map follows all the messages sent from person to person. Sequence Diagrams are used to show your team how objects in your program interact with each other to complete tasks. Now it's time for you to learn about Sequence Diagrams. Explain the tradeoff between cohesion and coupling.Apply design guidelines for modularity, separation of concerns, information hiding, and conceptual integrity to create a flexible, reusable, maintainable design.Translate between UML class diagrams and equivalent Java code.Express object-oriented models as Unified Modeling Language (UML) class diagrams.

Explain the difference between association, aggregation, and composition dependencies.Explain and apply different types of inheritance.Explain and apply object-oriented modeling principles and their purpose (e.g., abstraction, encapsulation, decomposition, generalization).Apply the Class Responsibility Collaborator (CRC) technique to analyze and design the object-oriented model for a problem.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.Īfter completing this course, you will be able to: And, you will be able to communicate these designs in a visual notation known as Unified Modelling Language (UML). You will discover how to create modular, flexible, and reusable software, by applying object-oriented design principles and guidelines. This course takes Java beginners to the next level by covering object-oriented analysis and design.
