Programación Orientada a Objetos

La Programación Orientada a Objetos (POO u OOP según sus siglas en inglés) es un paradigma de programación que usa objetos y sus interacciones para diseñar aplicaciones y programas de computadora. Está basado en varias técnicas,
- Modularidad,
-Polimorfismo
-Encapsulamiento.
Empezó a principios de la década de los 90. Actualmente muchos son los lenguajes de programación que soportan la orientación a objetos.
Los objetos son entidades que combinan estado, comportamiento e identidad:
La programación orientada a objetos expresa un programa como un conjunto de estos objetos, que colaboran entre ellos para realizar tareas. Esto permite hacer los programas y módulos más fáciles de escribir, mantener, reutilizar y volver a utilizar.
De aquella forma, un objeto contiene toda la información que permite definirlo e identificarlo frente a otros objetos pertenecientes a otras clases e incluso frente a objetos de una misma clase, al poder tener valores bien diferenciados en sus atributos. A su vez, los objetos disponen de mecanismos de interacción llamados métodos que favorecen la comunicación entre ellos. Esta comunicación favorece a su vez el cambio de estado en los propios objetos. Esta característica lleva a tratarlos como unidades indivisibles, en las que no se separan ni deben separarse el estado y el comportamiento.
Los métodos (comportamiento) y atributos (estado) están estrechamente relacionados por la propiedad de conjunto. Esta propiedad destaca que una clase requiere de métodos para poder tratar los atributos con los que cuenta. El programador debe pensar indistintamente en ambos conceptos, sin separar ni darle mayor importancia a ninguno de ellos. Hacerlo podría producir el hábito erróneo de crear clases contenedoras de información por un lado y clases con métodos que manejen a las primeras por el otro. De esta manera se estaría realizando una programación estructurada camuflada en un lenguaje de programación orientado a objetos.

Que es Objeto?

Un objeto es una cosa podemos percibir por algún sentido sobre la que se puede accionar y carece de autonomía de acción.
La consideración de algo como objeto depende del ámbito en el cual se está definiendo al mismo. Así, los objetos pueden ser:
materiales o reales, si poseen materia con forma definida;
abstractos, si sólo son conceptos sobre los que se puede accionar;
y toda cosa sobre la que se pueda accionar es un objeto semántico.
Lo dado en el conocimiento o aquello hacia lo que esta orientada la actividad cognoscente u otra actividad del sujeto.
