Java I/O, NIO and NIO.2 is a power-packed book that is an accelerated guide and reference on buffers, files, sockets, datagrams, and pipe channels as found in the Java I/O, NIO, and NIO.2 reference implementations. In this book, you'll also learn how and when to use selectors, regular expressions, including patterns, matchers and more. You'll learn how to work with Charsets, formatters and scanners. You'll - all in all - learn how to use and apply NIO, NIO.2 and the enhancements available.
After reading and using this 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.
Thought that it will be just book about i/o, how I was wrong... This book is a Swiss knife for any java developer that works with bytes in any type: text, files, streams, ip etc. I was empressed by the regex and socket structure chapters. Wish that all books will be structured like this. Definitely 6 stars of 5. ⭐️⭐️⭐️⭐️⭐️
