Each of the methods in the Human class contains a list of instructions that makes use of both the name and friend attributes.Ĭlass Main Criticism Įven though object-oriented programming is popular, some people think that it is bad and criticize it. This class contains the attributes name (for the name of the person) and friend (for the name of the friend). In the examples below, we create a class called Human. Objects is a term used to refer to instances of classes. Classes usually talk to one another to make changes to data in order to work in a way that the user wants. Classes are collections of different variables and procedures.In object-oriented programming, procedures are mainly known as methods. Procedures also exist in procedural programming languages. Procedures are lists of instructions telling the computer to take input, do some calculations or change data, and return the output to the user.In object-oriented programming, variables are mainly known as attributes. Variables also exist in procedural programming languages. Examples are the integer data type and the lists data structure. Variables can hold different types of information that are supported by the programming language.However, the object can be of different types: The main idea of object-oriented programming is that everything is an object. Some of these programming languages are: C++, Java, Ruby, Perl, Emarald, Sapphire, PHP, Python, C#, etc.
There are many programming languages that allow you to write computer programs in object-oriented programming. For example, Python allows for computer programs to be written both in object-oriented programming and in procedural programming. Most programming languages are a mix of different ways of writing computer programs.
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. 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. 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, which is called procedural programming. Object-oriented programming ( OOP) is a way of writing computer programs using " objects" to stand for data and methods.
