Java Programming 9th Edition

Java Programming, Ninth Edition, provides the beginning programmer with a guide to developing applications using the Java programming language. Java is popular among professional programmers because it can be used to build visually interesting graphical user interface (GUI) and Web-based applications. Java also provides an excellent environment for the beginning programmer—a student can quickly build useful programs while learning the basics of structured and object-oriented programming techniques. This textbook assumes that you have little or no programming experience. It provides a solid background in good object-oriented programming techniques and introduces terminology using clear, familiar language. The programming examples are business examples; they do not assume a mathematical background beyond high school business math. In addition, the examples illustrate only one or two major points; they do not contain so many features that you become lost following irrelevant and extraneous details. Complete, working programs appear frequently in each chapter; these examples help students make the transition from the theoretical to the practical. The code presented in each chapter also can be downloaded from the publisher’s website, so students easily can run the programs and experiment with changes to them. The student using Java Programming, Ninth Edition, builds applications from the bottom up rather than starting with existing objects. This facilitates a deeper understanding of the concepts used in object-oriented programming and engenders appreciation for the existing objects students use as their knowledge of the language advances. When students complete this book, they will know how to modify and create simple Java programs, and they will have the tools to create more complex examples. They also will have a fundamental knowledge about object-oriented programming, which will serve them well in advanced Java courses or in studying other object-oriented languages such as C++, C#, and Visual Basic.
