    • Students can also manipulate the code from the book's Companion Website or from the author's Website.
  • Outstanding, consistent and applied pedagogy:
    • Icons throughout identify hundreds of Software Engineering Observations; Good Programming Practices; Common Programming Errors; Portability Tips; Performance Tips, Testing and Debugging Tips, and Look-and-Feel Observations.
    • Provides hundreds of valuable programming tips and facilitates learning.
  • Extensive set of interesting exercises and substantial projects that enables students to apply what they've learned in each chapter.
  • Access to the Companion Website is available with the purchase of a new textbook. The Companion Website provides extra hands-on experience and study aids for no additional cost. It includes:
    • Hours of detailed, expert video walkthroughs – VideoNotes – of many of the book's live-code examples;
    • Post-assessment exams with hundreds of short answer questions (all with answers);
    • Hundreds of self-review exercises drawn from the text (with answers);
    • Hundreds of programming exercises from the main text (these exercises don't have answers in the main text, but half of these exercises have answers in the Companion Website);
    • Hundreds of tips that are marked with icons and show how to write code that's portable, reusable, and optimized for performance; and full-text searching and hyperlinking.
  • “Making a Difference” exercise sets encourage students to associate computers and the Internet with solving problems that really matter to individuals, communities, countries and the world.
    • These exercises encourage students to think for themselves as they explore complex social issues and increase awareness of important issues the world is facing.
    • Many of the exercises require students to conduct research on the web and weave the results into their problem-solving process.
  • The optional object-oriented design/UML 2 automated teller machine (ATM) case study is organized into two optional chapters that present the ATM’s design and complete code implementation.
  • Most of the programming exercises are titled for easy reference.
  • VideoNotes are step-by-step video tutorials specifically designed to enhance the programming concepts presented in Deitel, Java How to Program (Early Objects), 9e. Students can view the entire problem-solving process outside of the classroom–when they need help the most. VideoNotes are available with the purchase of a new copy of select titles. Go to www.pearsonhighered.com/videonotes for a brief VideoNotes demo.
