Java 5: files and java IO, software development

This book is the fifth in a series of books on software development. The programming language is Java, and the language and its syntax and semantic fills obviously much, but the books have also largely focus on the process and how to develop good and robust applications. As the previous book, this book has, however, only to a lesser extent focus on the process, but more on the language and details regarding Java. The subject of this book are files and what Java provides to IO, and the goal is in details to show how to manipulate files. Although the files today do not means exactly the same for practical programming, the processing of files is yet knowledge which is required to have in order to be able to work as a professional software developer. Finally, it is important to be aware that IO plays a crucial role in computer networking, and much of what follows will be used and expanded in the book Java 15 on network programming. Furthermore treat this book data representation, which are mostly deferred to an appendix, which also gives a brief introduction to the binary and hexadecimal numbers. The detailed data representation do not play a big role in everyday life, but also here is a topic that is necessary to have knowledge of, for example, in the context of computer networks. The book assumes that the reader has a knowledge corresponding to what is addressed in Java 3 and Java 4, but if you wish, the book can be postponed until you get the need.
