Object

• Encapsulates data and code
• Fields contain data
• Methods contain code for acting on the data
• Every object has its own copy of the data
• Same objects are typically grouped into a class
• Classes can also contain data and code shared among all objects
• Classes can be organised in an inheritance hierarchy
• Each derived class inherits the fields and methods of its base class
• Polymorphism allows objects of any derived class to be used as objects of the base class
