Software Expert Kent Beck Presents a Catalog of Patterns Infinitely Useful for Everyday Programming Great code doesn’t just function: it clearly and consistently communicates your intentions, allowing other programmers to understand your code, rely on it, and modify it with confidence. But great code doesn’t just happen. It is the outcome of hundreds of small but critical decisions programmers make every single day. Now, legendary software innovator Kent Beck—known worldwide for creating Extreme Programming and pioneering software patterns and test-driven development—focuses on these critical decisions, unearthing powerful “implementation patterns” for writing programs that are simpler, clearer, better organized, and more cost effective. Beck collects 77 patterns for handling everyday programming tasks and writing more readable code. This new collection of patterns addresses many aspects of development, including class, state, behavior, method, collections, frameworks, and more. He uses diagrams, stories, examples, and essays to engage the reader as he illuminates the patterns. You’ll find proven solutions for handling everything from naming variables to checking exceptions.

Programmers make hundreds of decisions a day. Occasionally they make large-scale decisions like those covered by Design Patterns. Far more frequently they make small-scale decisions--choosing names, organizing code logically, dividing programs into coherent parts. The cumulative effect of these hour-by-hour, minute-by-minute decisions is as significant as the effect of the design decisions in making code clear, flexible, and robust. This book is a catalog of the frequent decisions programmers make and the approaches to these decisions that result in code that communicates clearly. Programmers applying Implementation Patterns achieve code that is consistent, easy to read, and easy to modify. It sets out the "bag of tricks" common to excellent programmers in Java and similar languages. Implementation Patterns will appeal to programmers wishing to improve their individual practice, teams finding a common style, and language designers looking for abstractions to add to the next generation of programming languages. The days development teams are bigger, more spread out, and frequently forced to work with legacy applications. Now more than ever clear, communicative code is essential.
