Sams Teach Yourself Java in 24 Hours (7th Edition)

Sams Teach Yourself Java in 24 Hours (7th Edition) is the Chinese translation of the seventh edition of Sams Teach Yourself Java in 24 Hours by the American programmer and technical writer Rogers Cadenhead. It was translated by Hao Jisheng and published by Posts & Telecom Press. The book is organized into 24 one-hour lessons, each of which can be read in about an hour, making it suitable for complete beginners to study in sequence on their own. The content begins with understanding programming and setting up a Java development environment, then uses the first runnable program to lead readers through the complete process of writing, compiling and running code. It then covers language basics in turn—variables and data types, string handling, conditionals, loops and arrays—before moving on to creating objects and classes, describing object behavior and reusing class libraries, helping readers build a basic understanding of object-oriented programming. The second half moves on to building and laying out graphical user interfaces (Swing), event handling and input processing, and advanced topics such as data structures, exception handling, multithreading, inner classes and closures; it also covers file reading and writing, JAX-WS web services and Java2D graphics drawing, and ends with an Android app. Each chapter includes sample program listings, run output and code analysis, and ends with "Q&A," quizzes and exercises for readers to check their mastery. The book also includes appendices on using the NetBeans integrated development environment, further learning resources and setting up an Android development environment. At about 499,000 characters, it is positioned as a beginner's tutorial and can also be used by programmers familiar with other languages to quickly look up Java syntax.
