Samenvatting

How well do you know I/O? 'Java I/O, second edition' teaches you the I/O tricks and techniques used by the wizards and gurus of the Java world. This book will open your eyes to the powers and patterns of streaming I/O.

Java's I/O facilities are extraordinary flexible and simple to use, and provide everything from simple binary and text output to USB and Bluetooth communication. There's world-class support for internationalization, memory-mapped files, asynchronous I/O and more. Do you need to encrypt your files and network sockets for privacy and security? 'CipherInputStream' is what you want. Do you desire smaller, more compact output? 'ZipOutputStream' is what you're looking for. Is your network server buckling under the load of many clients? Selectors and channels could be your salvation.

All of that's in this book, covered in detail, with practical examples. Topics include:

Input and output streams;
Network sockets;
Filter streams, including buffered streams, data streams and pushback input streams;
Printf-style I/O;
ZIP and JAR archives;
Encryption and decryption;
Object serialization;
Buffers, channels, non-blocking I/O, and other 'new I/O' features;
Files, directories, file systems, and file choosers;
Readers, writers, and Unicode;
Serial and parallel ports, USB, and Bluetooth;
I/O programming for J2ME devices.

I/O is at the heart of every useful program, whether it's a backend server or a desktop application.
Without input or output, programs can't communicate. And poor I/O handling is often at the root of performance problems. This book shows you how to solve your I/O problems. 'Java I/O, second edition' is an essential resource for anyone who's writing in Java today.
