Presentation
Abstract class (in C++, pure virtual method): blueprint for a class without any implementation and thus cannot be instantiated Abstract class methods: not all must be abstract, some can be concrete Abstract class required: when at least one of the methods in the class is abstract Abstract method: require non-abstract derived classes to provide their own implementation of this method Interface class: an abstract class with public abstract methods all of which must be implemented in the inherited classes Interface class methods: all must be abstract and public and thus accessibility modifiers not needed Multiple interfaces: can be inherited Namespace class: classes are declared inside a namespace
