Synopses & Reviews
Learn Smalltalk's syntax, library, and environment, as well as fundamental programming and object-oriented development concepts, with Discovering Smalltalk, a comprehensive introduction to this powerful language. Author Wilf LaLonde, an expert in Smalltalk and object-oriented concepts, adopts an experimental approach that encourages you to think creatively and consider different methods for problem-solving. By completing various programming exercises and analyzing their results, you'll develop the skills necessary to write complex programs. In addition, numerous screen captures, case studies, and chapter overviews highlight important concepts and enhance learning. All programs and exercises are in Smalltalk/V. Features: provides a complete introduction to Smalltalk that encourages experimentation and creative problem-solving; 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; contains a reference to the most important classes in the Smalltalk library, including objects, strings, numbers, and characters; illustrates how the Smalltalk environment supports evolutionary software developments using workspaces, inspectors, browsers, and debuggers; and discusses the application of object-oriented methodologies to software development in Smalltalk.
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.
