Understanding Inheritance

  • Classes can only inherit from one Abstract Class
  • Classes can implement multiple Interfaces
  • Classes can replace none, some or all of an Abstract Class’s Fields, Properties, Constructors, Methods and Events
  • Classes must implement every Field, Property, Constructor, Method and Event in an Interface
  • You would normally create an Abstract Class for the overarching idea of your Classes, and create Interfaces for the details of each specific type of Class using the Abstract Class
