In-depth analysis of Java network programming: from entry to proficiency

Java network programming has always been a hot topic for programmers to learn more. The book "In-depth Analysis of Java Network Programming: From Beginner to Master" carefully written by PHP editor Xiaoxin systematically introduces the basic knowledge and advanced technologies of Java network programming to help readers from entry to master. Through in-depth analysis, readers can not only master the core concepts and principles of network programming, but also learn practical application skills and improve their skills in the field of Java network programming.

Basic concepts

• Network basics: Understand network protocols, tcp/IP models and network topology.
• Java Network API: Familiar with the Java.net package, including Socket, ServerSocket and URLConnection and other classes.
• Network communication models: Understand the client-server, peer-to-peer, and multicast communication models.

Client Programming

• Client Socket: Create a client Socket and connect to the server.
• Data sending and receiving: Use input/output streams to send and receive data.
• Non-blocking IO: Optimize client performance, use Selector to implement non-blocking IO.
• Multi-client connection management: Handling multi-client Concurrent connections.

Server-side programming

• Server Socket: Create ServerSocket and listen for client connections.
• Client connection processing: Accept client connections and create new threads or process processing.
• Data concurrency management: Use synchronization mechanism to handle concurrent data access.
• Server configuration: Optimize server performance, adjust the number of connections, timeout and thread pool size.

Advanced Theme

• Multi-threaded programming: Use Multi-threading to handle concurrent connections and IO operations.
• Protocol analysis: Understand and analyze network protocols, such as Http, FTP and SMTP.
• Network Security: Protect network communications from attacks and implement encryption, authentication, and access control.
• Web Services: Build and deploy Java-based WEB services using REST and SOAP technologies.
• Big data communication: Processing big data volume communication, using frameworks such as Apache hadoop.

Case Application

• Instant Messaging System: Utilize the client-server model to build instant messaging applications.
• File sharing application: Use the peer-to-peer network model to achieve file sharing.
• Network monitoring system: Use multicast communication to monitor network devices.
• Distributed computing system: Use Java RMI to implement distributed computing.
