Written in an informal, conversational, and humorous style, the second edition of Introduction to Programming Using Processing makes learning programming a fun experience. The freely-available Processing language is ideal for a first course in programming. The simple-to-access graphics and multimedia capabilities of the language let students develop eye-catching, animated programs, instead of traditional programs that print text to the console. The text takes a ""classes-later"" approach, focusing on basics, using objects, selection, iteration, topdown design, and arrays, before writing classes. Every example is presented in the context of the RADIS (Requirements / Analyze / Design / Implement / Support) framework, with considerable attention paid to design. Other positive habits, like good commenting practice and coding style, are emphasized as well.
