Object-oriented programming - definition of Object-oriented programming in Encyclopedia (3477 words)
Meta class programming (see Meta class) for example is a demanding skill, and OOP programs can have a complex web of shared or distinct responsibilities, attributes and methods.
The structure and behavior of an object are defined by a class, which is a definition, or blueprint, of all objects of a specific type.
Also, another common example is that a person object created from a child class cannot become an object of parent class because a child class and a parent class inherit a person class but class-based languages mostly do not allow to change the kind of class of the object at runtime.
