Java I/O, NIO, and NIO.2 is a power-packed book that accelerates your mastery of Java's various I/O APIs. In this book, you'll learn about classic I/O APIs (File, RandomAccessFile, the stream classes and related types, and the reader/writer classes). Next, you'll learn about NIO's buffer, channel, selector, regular expression, charset, and formatter APIs. Finally, you'll discover NIO.2's offerings in terms of an improved file system interface, asynchronous I/O, and the completion of socket channel functionality.

After reading and using thi book, you'll gain the accelerated knowledge and skill level to really build applications with efficient data access, especially for today's cloud computing streaming data needs.

What you’ll learn

How to set permissions and more with the classic File classHow to build a flat file database with RandomAccessFileGet to know the byte array, file, filter, and other kinds of streamsMaster serialization and externalizationDiscover character streams and their associated writers/readersTour the buffer APIsWork with channels to transfer buffers to and from I/O servicesFind out about selectors and readiness selectionMaster regular expressionsDiscover charsets and their association with Java's String< classTake advantage of the formatter API to create formatted outputHow to customize the formatter APIExplore the improved file system interfaceDiscover asynchronous I/O and its association with futures and completion handlersEncounter socket channel improvements, including multicasting
