Summary of Intro to Object Oriented Programming - Crash Course

00:00:00 - 00:30:00

This video introduces the basics of Object Oriented Programming (OOP). It discusses how OOP can help to organize and store data more efficiently, and how objects are created and relate to each other. It also covers the principles of encapsulation, abstraction, and inheritance.

• 00:00:00 In this lecture, we'll be exploring what object-oriented programming is, and how it works. We'll be discussing how primitive data types such as bytes, ints, floats, doubles, and booleans work, and how structures can help organize and store data more efficiently. We'll also explore how objects are created and how they relate to each other.
• 00:05:00 Object-oriented programming provides a way to group related data and functions together, allowing for complex programming without having to code everything separately. In this Crash Course, we'll be looking at the first of four main principles of OOP - encapsulation. We'll see how this is used in the context of the chess example from the previous section, and how it makes it easy to track and manage related attributes.
• 00:10:00 Abstraction is the idea of hiding essential details from users of a class, while encapsulation is the practice of hiding data from other classes. These concepts are important when working on large and complex programs, as it can be difficult to focus on the big picture while programming. This section will be discussing the fourth principle of object-oriented programming, abstraction.
• 00:15:00 In object-oriented programming, an interface is a predetermined set of methods that two classes are allowed to use to communicate with each other. This prevents different pieces of the program from becoming completely coupled together, and helps to prevent errors in communication. inheritance is the principle that allows one class to derive other classes from it, and in this video, we'll look at an example.
• 00:20:00 In this crash course on object oriented programming, we discuss the three main access modifiers: public, private, and protected. We also discuss polymorphism, which describes methods that can take on many forms. Finally, we discuss the principle of inheritance, which describes how classes can be related to one another.
• 00:25:00 Polymorphism is the ability of a method to take on different forms depending on the class hierarchy it is called from. This works both dynamically and statically. Overloading allows methods with the same name to have different effects, but is potentially tricky to implement.
• 00:30:00 This video introduces the basics of Object Oriented Programming (OOP). If you're interested in learning more about OOP, be sure to check out other videos in the Crash Course series.
