Testing and debugging classes in Java; Intro Java course Lesson 6 Video 8

This series of videos is suitable for programmers with minimal (or no) programming experience who want to learn Java. This is the thirty-ninth video in the Introductory Java series, and the eighth video in lesson 6 (classes and objects). In this video we'll look at some theory that helps you develop a set of test cases for a class, as well as some common class errors.

There is a suggested (free) book below that you could read along with the videos lessons. However, the video is very straightforward and can also stand alone or accompany any other introductory Java textbook. Let's have some fun learning to program in Java!
