There are many benefits to learning OO programming, and especially its modularity. Modularity lets you break your code into smaller parts. This makes it easier to troubleshoot, gives you the powerful ability to reuse your code elsewhere, and makes your code adaptive and flexible. Although this course uses Java to introduce OO programming, it should prepare you to explore other languages since you can apply these concepts to nearly any other OO programming language.
If you'd like to learn more about Java after you complete this course, you can continue your studies in CS101: Introduction to Computer Science I.
First, read the course syllabus. Then, enroll in the course by clicking "Enroll me in this course". Click Unit 1 to read its introduction and learning outcomes. You will then see the learning materials and instructions on how to use them.
In this unit, we will explore the concepts that make OO programming different from the traditional structural design approach. Although Java supports the traditional approach, OO programming has allowed for a more robust, flexible programming design paradigm that has made it the industry standard for most new programs.
Completing this unit should take you approximately 1 hour.
In this unit, we will explore objects and take a look at how they differ from classes. From there, we will explore some of the key concepts of OO programming that make it such a desirable choice. These concepts include inheritance, polymorphism, and abstract classes, which allow multiple classes to interact. Encapsulation is the idea of bundling all of your data and methods into a single unit, and restricting the direct access of certain components of your objects, protecting those objects' data from outside manipulation. Finally, we will explore the concept of decoupling, which is how we separate classes to decrease their dependency on one another.
Completing this unit should take you approximately 2 hours.
