To give students the "training wheels" they need to rapidly begin using sophisticated Java features, the authors introduce a complete object-oriented graphics library. Using it, students can immediately begin programming simple graphics and animations, and literally see the results of their code. Students learn core language features as they're ready - and master powerful features such as concurrency far sooner than in conventional treatments.
So, truth in advertising: this text was written by not one, not two, but _three_ of my former professors. But, while I certainly like the book well enough, it was my students who really endorsed it. As I noted in my review of Objects First with Java, finding a text that presents both the language and the conceptual design material well to the satisfaction of both teachers and students is really hard. But Eventful Java seems to fit the bill (in my classroom, at least).
We used this as a text for our first semester of a "post-AP" course, covering the AP material in a fairly self-paced manner while also building a toolkit for more ambitious work in the second semester. And this worked great: solid text with suitably engaging and challenging problem sets.
This is the first time in ten years that I've used a Java text for a second year.
