Think Java, 2nd Edition

Preface

Think Java is an introduction to computer science and programming intended for readers with little or no experience. We start with the most basic concepts and are careful to define all terms when they are first used. The book presents each new idea in a logical progression. Larger topics, like control flow statements and object-oriented programming, are divided into smaller examples and introduced over the course of several chapters.

This book is intentionally concise. Each chapter is 10–12 pages and covers the material for one week of a college course. It is not meant to be a comprehensive presentation of Java, but rather, an initial exposure to programming constructs and techniques. We begin with small problems and basic algorithms and work up to object-oriented design. In the vocabulary of computer science pedagogy, this book uses the objects late approach.

The Philosophy Behind the Book

Here are the guiding principles that make the book the way it is:

One concept at a time

We break down topics that give beginners trouble into a series of small steps, so that they can exercise each new concept in isolation before continuing.

Balance of Java and concepts

The book is not primarily about Java; it uses code examples to demonstrate computer science. Most chapters start with language features and end with concepts.

Conciseness

An important goal of the book is to be small enough so that students can read and understand the entire text in a one-semester college or AP course.
