An early introduction to object-oriented programming techniques , beginning in Chapter 2, provides extensive practice with objects and classes before students are asked to write their own classes. Horstmann's clear explanations follow the beginner's thinking process, providing examples and analogies, and anticipating where they may get confused or make mistakes. The Testing Track identifies and emphasizes the test-driven approach to programming. The Graphics Track integrates optional graphics material into the chapters where it best fits. Self-Check Questions test understanding, not memorization, and can be used as springboards to a deeper discussion of key concepts in each section. Excellent problems, questions, and project suggestions.
