NIO Package

The NIO package in Java introduces a powerful alternative to the traditional I/O classes. If you've ever felt limited by the existing Java I/O classes when dealing with files, streams, or buffers, you’re in for a treat. NIO, which stands for Non-blocking I/O, is designed to handle many of the common pain points associated with I/O operations.

With NIO, you get the ability to handle files in a more flexible, efficient, and powerful way. You can work with larger files, manage file systems, and perform I/O operations asynchronously.

This chapter will guide you through the essentials of the NIO package, its components, and how to leverage its capabilities in your applications.
