Most modern programming languages, such as Java, C#, Ruby, and Python, are object-oriented languages, which help group individual bits of code into a complex and coherent application. However, object-orientation itself is not a language; it's simply a set of ideas and concepts.
Let Simon Allardice introduce you to the terms—words like abstraction, inheritance, polymorphism, subclass—and guide you through defining your requirements and identifying use cases for your program. The course also covers creating conceptual models of your program with design patterns, class and sequence diagrams, and unified modeling language (UML) tools, and then shows how to convert the diagrams into code.
We are at the end of the course, but there is still a lot more that you can learn and understand about object- oriented programming analysis and design. You can develop these skills for many years both in depth and in subtlety. Now most people first approach object orientation believing it's a set of absolute rules and predefined structures. But as we've explored, it's simply an approach that brings with it a variety of tools and techniques. It's true that there is no one true way but there are certainly best practices, and you have the choice of which ones are most useful for you.
It's a good idea to revisit this content now and again. You will find new ideas, and things that will have new meaning the second or even the third time around. And thanks for watching. See you next time.
