Abstract
Programming in terms of interfaces is a fundamental concept in OO systems in general and the Gang-of-Four design patterns in particular. Nonetheless, many Java programmers make little use of interfaces (and overuse the extends relationship). This chapter explains the problems with extends and how you can solve some of those problems with interfaces. I also introduce a few of the Creational patterns that simplify interface-based programming.
