Summary

In this chapter, you learned how to recognize real-world elements and translate them into the different components of the object-oriented paradigm: classes, attributes, methods, and instances. You understood the differences between classes (blueprints or templates) and the objects (instances). We designed a few classes with attributes and methods that represented blueprints for real-life objects. Then, we improved the initial design by taking advantage of the power of abstraction, and we specialized in the Ellipse class.

Now that you have learned some of the basics of the object-oriented paradigm, you are ready to start creating classes and instances in Python, JavaScript, and C# in the next chapter.
