Head First Java: A Brain-Friendly Guide (3 ed)

Kathy has been interested in learning theory since her days as a game designer for Virgin, MGM, and Amblin and a teacher of New Media Authoring at UCLA. She was a master Java trainer for Sun Microsystems, and she founded JavaRanch.com (now CodeRanch.com), which won Jolt Cola Productivity awards in 2003 and 2004.In 2015, she won the Electronic Frontier Foundation's Pioneer Award for creating skillful users and building sustainable communities. Kathy's recent focus has been on cutting-edge movement science and skill acquisition coaching, known as ecological dynamics or Eco-D. Her work using Eco-D for training horses is ushering in a far, far more humane approach to horsemanship, causing delight for some (and sadly, consternation for others). Those fortunate (autonomous!) horses whose owners are using Kathy's approach are happier, healthier, and more athletic than their traditionally trained fellows.

Before Bert was an author, he was a developer, specializing in old-school AI (mostly expert systems), real-time OSes, and complex scheduling systems. In 2003, Bert and Kathy wrote Head First Java and launched the Head First series. Since then, he's written more Java books and consulted with Sun Microsystems and Oracle on many of their Java certifications. He trains authors and editors to create books that teach well. Of the hundreds of authors he's trained, many have gone on to write best-selling books. Bert's a Go player, and in 2016 he watched in horror and fascination as AlphaGo trounced Lee Sedol. Recently he's been using Eco-D (ecological dynamics) to improve his golf game and to train his parrotlet Bokeh. You can email Bert at CodeRanch.com.
