Object-Oriented Programming Concepts

What is an Object? An object is a software bundle of related state and behavior. Software objects are often used to model the real-world objects that you find in everyday life.
What is a Class? A class is a blueprint or prototype from which objects are created.
What is Inheritance? Inheritance provides a powerful and natural mechanism for organizing and structuring your software.
What is an Interface? An interface is a contract between a class and the outside world. When a class implements an interface, it promises to provide the behavior published by that interface.
What is a Package? A package is a namespace for organizing classes and interfaces in a logical manner. Placing your code into packages makes large software projects easier to manage.
