2017 Java NIO Programing

Java NIO，全称为Non-Blocking Input/Output（非阻塞输入/输出），是Java标准库提供的一种替代传统I/O模型的新技术。在Java 1.4版本中引入，NIO提供了一种全新的I/O编程方式，使得Java开发者能够更高效地处理I/O操作...

### NIO 入门知识点详解 #### 一、NIO 的引入及其背景 - **NIO 的起源**：NIO（New Input/Output）库是在 JDK 1.4 中引入的，旨在解决传统 Java I/O 操作的局限性和性能瓶颈。 - **改进目标**：NIO 通过提供高速...

java_NIO_入门(良好排版格式).pdf,关于JAVA的IO编程方面的知识,比较深入的介绍了NIO的知识

Java NIO深入探讨了1.4版的I/O新特性，并告诉您如何使用这些特性来极大地提升您所写的Java代码的执行效率。这本小册子就程序员所面临的有代表性的I/O问题作了详尽阐述，并讲解了如何才能充分利用新的I/O特性所提供的各种潜能。您将通过实例学会如何使用这些工具来解决现实工作中常常遇到的I/O问题，并了解这些新特性如何对响应速率、可伸缩性和可靠性产生直接影响。 NIO API是对1.3版I/O特性的补充而非取代，因此，何时使用新的API，何时老的1.3版I/O API更适合特定应用，也是您将学习的内容。

This book covers all the important aspects involved in developing NIO.2-based applications. It provides clear instructions for getting the most out of NIO.2 and offers many exercises and case studies to spice up your Java 7 applications with the new I/O capabilities. You will learn to develop NIO.2 applications, beginning with simple but essential stuff and gradually moving on to complex features such as sockets and asynchronous channels.

Input/output (I/O) is not a sexy subject, but it’s an important part of non-trivial applications. This book introduces you to most of Java’s I/O capabilities as of Java 8 update 51. Chapter 1 presents a broad overview of I/O in terms of Java’s classic I/O, New I/O (NIO), and NIO.2 categories. You learn what each category offers in terms of its capabilities, and you also learn about concepts such as paths and Direct Memory Access. Chapters 2 through 5 cover classic I/O APIs. You learn about the File and RandomAccessFile classes along with streams (including object serialization and externalization) and writers/readers. Chapters 6 through 11 focus on NIO. You explore buffers, channels, selectors, regular expressions, charsets, and formatters. (Formatters were not introduced with the other NIO types in Java 1.4 because they depend on the variable arguments capability that was introduced in Java 5.) NIO is missing several features, which were subsequently provided by NIO.2. Chapters 12 through 14 cover NIO.2’s improved file system interface, asynchronous I/O, and the completion of socket channel functionality. Each chapter ends with assorted exercises that are designed to help you master its content. Along with long answers and true/false questions, you are often confronted with programming exercises. Appendix A provides the answers and solutions. Appendix B provides a tutorial on sockets and network interfaces. Although not directly related to classic I/O, NIO, and NIO.2, they leverage I/O capabilities and are mentioned elsewhere in this book.
