Java: A Beginner's Guide

Java: A Beginner's Guide is the Chinese translation of an introductory Java tutorial by American programmer and computer book author Rogers Cadenhead, laid out in 24 chapters that take readers "from zero to building a project." Written for Java 9 and using the free NetBeans as the development tool, it starts with installing and configuring the development environment and writing the first runnable Java program, first explaining clearly how Java programs are written and how they work, then moving on to variables and data types, string handling, conditionals and loops, arrays, methods, and other basic syntax. Once the basics are solid, the book moves into object orientation: objects and classes, inheritance, interfaces, inner classes and closures, data structures, exception catching and handling, threads and reactive programs, and introduces graphical user interface topics such as fonts, colors, and drawing. The final part turns to practical applications, including creating interactive web programs and HTTP clients, reading and writing files and XML data, writing Minecraft mods in Java, and developing Android applications. The book continues the "Read Less, Do More" teaching approach: every chapter includes sample program listings, sample output, and code analysis, and ends with frequently asked questions, answers, exercises, and quizzes; three kinds of sidebars—"Note," "Tip," and "Warning"—point out difficulties, shortcuts, and common pitfalls at any moment, helping readers understand concepts by doing.
