什么是面向对象 ？什么是object-oriented？

最好详细一点的解释，最好是英文版的解释

Object-oriented programming (OOP) is a programming paradigm that uses "objects" – data structures consisting of datafields and methods
together with their interactions – to design applications and computer
programs. Programming techniques may include features such as information hiding, data abstraction, encapsulation, modularity, polymorphism, and inheritance. It was not commonly used in mainstream software application development until the early 1990s. Many modern programming languages now support OOP.

在java中的表现就是所有东西都是用class（类）包着的
