Smalltalk And Object Orientation

This book was originally written to support an introductory course in Object Orientation through the medium of Smalltalk (and VisualWorks in particular). However, it can be used as a book to teach the reader Smalltalk, to introduce object orientation as well as present object oriented design and analysis. It takes as its basic premise that most Computer Scientists I Software Engineers learn best by doing rather than from theoretical notes. The chapters therefore attempt to introduce concepts by getting you the reader to do things, rather than by extensive theoretical discussions. This means that these chapters take a hands-on approach to the subject and assume that the student/reader has a suitable Small talk environment available to them. The chapters are listed below and are divided into six parts. The reader is advised to work through Parts 1 and 3 thoroughly in order to gain a detailed understanding of object orientation. Part 2 then provides an introduction to the Smalltalk environment and language. Other chapters may then be dipped into as required. For example, if the reader wishes to hone their Smalltalk skills then the chapters in Part 4 would be useful. However, if at that point they wish to get on and discover the delights of graphical user interfaces in Smalltalk, then Part 5 could be read next. Part 6 presents some more advances subjects such as metaclasses and concurrency which are not required for straight forward Small talk development.

A straightforward, step-by-step introduction to clear and elegant object-oriented programming. Using a language that's perfect for this kind of programming, the book has been tested in numerous courses and workshops over ten years. Programming Smalltalk is particularly suited for readers with no prior programming knowledge. Starting from the first principles of programming, it teaches you how to use and create algorithms (reusable rules for problem-solving) and the basic building blocks of software. It goes on to explain how to develop complete applications and has a whole chapter on web applications as well as case studies. Now translated into English, this edition was completely revised to be consistent with the latest version of Cincom® VisualWorks®, a professional Smalltalk environment. All examples were created using VisualWorks, which is available without cost for educational purposes, and can be downloaded and installed on any up-to-date computer.

More than a guide to the Smalltalk language.

"There are few books that show how to build programs of any kind. One common theme is compiler building, and there are shelves full of them. There are few others. It's an area, or a void, that needs filling. this book does a great job of showing how to build numerical analysis programs." -David N. Smith, IBM T J Watson Research Center Numerical methods naturally lend themselves to an object-oriented approach. Mathematics builds high- level ideas on top of previously described, simpler ones. Once a property is demonstrated for a given concept, it can be applied to any new concept sharing the same premise as the original one, similar to the ideas of reuse and inheritance in object-oriented (OO) methodology. Few books on numerical methods teach developers much about designing and building good code. Good computing routines are problem-specific. Insight and understanding are what is needed, rather than just recipes and black box routines. Developers need the ability to construct new programs for different applications. Object-Oriented Implementation of Numerical Methods reveals a complete OO design methodology in a clear and systematic way. Each method is presented in a consistent format, beginning with a short explanation and following with a description of the general OO architecture for the algorithm. Next, the code implementations are discussed and presented along with real-world examples that the author, an experienced software engineer, has used in a variety of commercial applications. Features: Reveals the design methodology behind the code, including design patterns where appropriate, rather than just presenting canned solutions. Implements all methods side by side in both Java and Smalltalk. This contrast can significantly enhance your understanding of the nature of OO programming languages. Provides a step-by-step pathway to new object-oriented techniques for programmers familiar with using procedural languages such as C or Fortran for numerical methods. Includes a chapter on data mining, a key application of numerical methods.

This text describes the design goals and language features of object-oriented languages without viewing them from the perspective of any particular language. The author discusses Smalltalk-80 and C++ so students can understand how these concepts are realized. It provides coverage of the object model from a software design and language feature perspective, as well as covering key object-oriented principles - date abstraction, inheritance, polymorphism, and dynamic binding. Detailed coverage of Smalltalk and C++ emphasize their similarities and differences in terms of design goals, language features, and usage. Also discussed are: the benefits of the object model; the latest extensions to C++; and the application of object-oriented concepts to the development of large software projects. Chapter summaries, extensive exercises, and a glossary of object-oriented terminology support the text.

This book provides an introduction to the understanding and use of object-oriented methodologies for engineering problem solving with a specific emphasis on analysis and design. (Object-oriented programming is a general computer language methodology. The name comes from the focus on describing problems in terms of objects, both physical and conceptual).
