Abstract
Base Classes
lAbstract base
classes can help with this issue
•Because if the
methods from them are ever directly called you will find out immediately that something is
wrong
•The intent, as with C++, is to create a common
interface
•So that the derived classes can express their
uniqueness!
•All derived class
methods that match the signature of the base class will be called using dynamic binding
•This is created by
making one or more abstract methods in the base class:
abstract void func(); //with no body
