Class Summary

Class	Description
Authenticator	The class Authenticator represents an object that knows how to obtain authentication for a network connection.
ContentHandler	The abstract class ContentHandler is the superclass of all classes that read an Object from a URLConnection.
DatagramPacket	This class represents a datagram packet.
DatagramSocket	This class represents a socket for sending and receiving datagram packets.
DatagramSocketImpl	Abstract datagram and multicast socket implementation base class.
HttpURLConnection	A URLConnection with support for HTTP-specific features.
Inet4Address	This class represents an Internet Protocol version 4 (IPv4) address.
Inet6Address	This class represents an Internet Protocol version 6 (IPv6) address.
InetAddress	This class represents an Internet Protocol (IP) address.
InetSocketAddress	This class implements an IP Socket Address (IP address + port number) It can also be a pair (hostname + port number), in which case an attempt will be made to resolve the hostname.
JarURLConnection	A URL Connection to a Java ARchive (JAR) file or an entry in a JAR file.
MulticastSocket	The multicast datagram socket class is useful for sending and receiving IP multicast packets.
NetPermission	This class is for various network permissions.
NetworkInterface	This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface.
PasswordAuthentication	The class PasswordAuthentication is a data holder that is used by Authenticator.
ServerSocket	This class implements server sockets.
Socket	This class implements client sockets (also called just "sockets").
SocketAddress	This class represents a Socket Address with no protocol attachment.
SocketImpl	The abstract class SocketImpl is a common superclass of all classes that actually implement sockets.
SocketPermission	This class represents access to a network via sockets.
URI	Represents a Uniform Resource Identifier (URI) reference.
URL	Class URL represents a Uniform Resource Locator, a pointer to a "resource" on the World Wide Web.
URLClassLoader	This class loader is used to load classes and resources from a search path of URLs referring to both JAR files and directories.
URLConnection	The abstract class URLConnection is the superclass of all classes that represent a communications link between the application and a URL.
URLDecoder	Utility class for HTML form decoding.
URLEncoder	Utility class for HTML form encoding.
URLStreamHandler	The abstract class URLStreamHandler is the common superclass for all stream protocol handlers.

Exception Summary

Exception	Description
BindException	Signals that an error occurred while attempting to bind a socket to a local address and port.
ConnectException	Signals that an error occurred while attempting to connect a socket to a remote address and port.
MalformedURLException	Thrown to indicate that a malformed URL has occurred.
NoRouteToHostException	Signals that an error occurred while attempting to connect a socket to a remote address and port.
PortUnreachableException	Signals that an ICMP Port Unreachable message has been received on a connected datagram.
ProtocolException	Thrown to indicate that there is an error in the underlying protocol, such as a TCP error.
SocketException	Thrown to indicate that there is an error in the underlying protocol, such as a TCP error.
SocketTimeoutException	Signals that a timeout has occurred on a socket read or accept.
UnknownHostException	Thrown to indicate that the IP address of a host could not be determined.
UnknownServiceException	Thrown to indicate that an unknown service exception has occurred.
URISyntaxException	Checked exception thrown to indicate that a string could not be parsed as a URI reference.

Package java.net Description

Provides the classes for implementing networking applications. Using the socket classes, you can communicate with any server on the Internet or implement your own Internet server. A number of classes are provided to make it convenient to use Universal Resource Locators (URLs) to retrieve data on the Internet.
