15. The java.net Package

The package java.net contains classes and interfaces that provide a powerful infrastructure for networking in Java. These include:

• The URL class for basic access to Uniform Resource Locators (URLs).

• The URLConnection class, which supports more complex operations on URLs.

• The Socket class for connecting to particular ports on specific Internet hosts and reading and writing data using streams.

• The ServerSocket class for implementing servers that accept connections from clients.

• The DatagramSocket, MulticastSocket, and DatagramPacket classes for implementing low-level networking.

• The InetAddress class, which represents Internet addresses.

Figure 15.1 shows the class hierarchy for the java.net package.
