In Structured Programming, programs are designed around the tasks to be solved.

In object-oriented programming, the program is designed around the objects in the problem domain.

How to recognize objects:
● Analogy ----> Classification
Class is the abstract object of a thing. It is an instance of a class (instantiation-> new)

A class is a set of objects with the same attributes and behaviors.

In software systems, we use classes to simulate entities in real life (the simulation has a line)

Classes do not exist in the true sense, but are defined in the concept of long-lasting people.

Strong language: mandatory (mandatory data type)
Weak language: weakening (not required to be defined)
Custom class:

Class Person [identifier ]{
// Attributes
Public $ name;
Public $ birth;
// Action
Function useTools (){

}
}
