Java Network Programming Practice

This repository contains examples and exercises related to Java's NIO (Non-blocking I/O). It covers the three main components of NIO, network programming, zero-copy techniques, I/O models, and the Netty framework.

Features

NIO (Non-blocking I/O): Advanced I/O operations for high scalability.
Zero-Copy: Efficient data transfer techniques to minimize CPU usage.
I/O Models: Implementation of different I/O models including synchronous and asynchronous models.
Netty Framework: Exercises and examples using the Netty framework for building network applications.

NIO Components

Java NIO introduces three primary components that are key to its non-blocking I/O capabilities:

Channels: Channels represent open connections to entities such as hardware devices, files, or sockets. They are similar to streams but provide more versatile functionality and can be both readable and writable.
Buffers: Buffers are containers for data that is being transferred between a channel and an application. Unlike streams, buffers can be read from and written to, making them essential for handling data in NIO.
Selectors: Selectors allow a single thread to manage multiple channels, enabling non-blocking I/O operations. A selector can monitor multiple channels for events (such as data arrival or connection requests), facilitating efficient resource utilization.

Example: MultiThreadServer

The MultiThreadServer example demonstrates how to use these NIO components to create a scalable, multi-threaded server that can handle multiple client connections efficiently.

Getting Started
