  1. Java provides robust support for networking through its java.net package, which includes classes and interfaces for building networked applications. These tools enable developers to create programs that communicate over networks using protocols like TCP, UDP, HTTP, and more.

    Core Networking Features in Java

    Java's networking capabilities are built into the java.net package, which provides classes such as Socket, ServerSocket, DatagramSocket, URL, and InetAddress. These classes allow developers to perform tasks like establishing connections, sending/receiving data, and resolving hostnames.

    Key Classes and Their Uses:

    • Socket: Enables TCP communication between a client and server.

    • ServerSocket: Listens for incoming TCP connections on a specified port.

    • DatagramSocket: Facilitates connectionless communication using UDP.

    • URL: Represents a Uniform Resource Locator for accessing web resources.

    • InetAddress: Provides methods to retrieve IP addresses and hostnames.

    Example: Basic Socket Programming
