Abstract
An abstract class provides a partial implementation that other classes can build upon. When a class is declared as abstract it means that the class can contain incomplete methods that must be implemented in subclasses, in addition to normal class members. These methods are left unimplemented and only specify their signatures, while their bodies are replaced by semicolons.
