  • Provides a comprehensive introduction to Smalltalk that encourages readers to experiment and evaluate various problem-solving methods.
  • Demonstrates the power and flexibility of Smalltalk's object-oriented development environment.
  • Presents detailed coverage of fundamental object-oriented programming concepts, such as objects, parts, methods, classes, and inheritance.
  • Incorporates a reference to the most important classes in the Smalltalk library, including objects, strings, numbers, and characters.
  • llustrates how the Smalltalk environment supports evolutionary software developments using workspaces, inspectors, browsers, and debuggers.
  • Integrates case studies on airline reservation systems, banking, the phone book, and other realistic uses of Smalltalk.
  • Contains numerous pedagogical aids, including screen captures, programming exercises, and chapter summaries, to facilitate learning.

What Reviewers are Saying

"This book provides a great introduction to Smalltalk. The coverage is excellent, both in depth and breadth. It is a welcome addition to the few available Smalltalk books."
Michael Hennessy, University of Oregon

"I like the book's experimental approach to learning, it explicitly encourages the user to try more problems and offers continual encouragement. he screens and figures are the book's greatest assets. The writing is excellent, it is clear and concise."
MaryAnn Robbert, Bentley College

"The screen captures and figures are good. Both the exercises and program code are very well presented, formatted, and commented. The author has a strong understanding of object-oriented and Smalltalk programming and communicates it well."
Craig Larman, Simon Fraser University

"I enjoyed reading this book, it is really the only book that I have seen that is suitable for an introductory reader. It is thorough and very well written and the examples are exceptionally well done."
Brian Malloy, Clemson University

An expert in Smalltalk, Lalonde provides an up-to-date introduction to this language in this comprehensive new book. Readers learn Smalltalk's syntax, library, and environment as well as fundamental programming and object-oriented development concepts. The author takes an experimental approach that encourages creative thinking and the use of different problem-solving techniques. This approach helps readers develop the skills and the confidence necessary for complex programming as they complete various programming exercises and analyze their results.

Professor LaLonde enhances learning by including numerous screen captures throughout the book to show the results of each of the programming experiments. Additionally, a series of case studies demonstrate real-world applications of Smalltalk.

Discovering Smalltalk is ideal both for those who have never programmed before and for experienced programmers who want to learn this powerful object-oriented language.
