Object-oriented programming

Object-oriented programming (OOP) is a way of writing computer programs using "objects" to stand for data and methods. Often, computer programs that are not object-oriented are a list of instructions for the computer, telling it to do certain things in a certain way. This is called procedural programming. However, in object-oriented programming, computer programs use objects that talk to one another to change the data in those objects and to work in a way that the user wants. Because of the way object-oriented programming is designed, it helps the developer by allowing for code to be easily reused by other parts of the program or even by other people.

Most programming languages are a mix of different ways of writing computer programs (called programming paradigms). For example, Python allows for computer programs to be written both in object-oriented programming and in procedural programming. There are many programming languages that allow you to write computer programs in object-oriented programming. Some of these programming languages are: C++, Java, Ruby, Perl, Emarald, Sapphire, PHP, Python, C#, etc.
