Understanding Interfaces & Abstract Classes

  • Work out the structure of your Class before you write any code
  • The Interface and Abstract Classes you need to create are not always immediately apparent
  • If you are working on a new Class and realize the form is wrong, don’t waste time trying to modify it, you’re usually better off starting over
  • Don’t become beholden to your Class’s structure
  • Try not to let non-programmers dictate the form of your Classes
