Class Summary

Class	Description
Authenticator	An implementation of this class is able to obtain authentication information for a connection in several ways.
CacheRequest	CacheRequest is a kind of channel for storing resource data in the ResponseCache.
CacheResponse	A response cache entry.
ContentHandler	This class converts the content of a certain format (i.e.
CookieHandler	This class provides a way to manage cookies with a HTTP protocol handler.
CookieManager	This class provides a concrete implementation of CookieHandler.
DatagramPacket	This class represents a datagram packet which contains data either to be sent or received through a DatagramSocket.
DatagramSocket	This class implements a UDP socket for sending and receiving DatagramPacket.
DatagramSocketImpl	The abstract superclass for datagram and multicast socket implementations.
HttpCookie	An opaque key-value value pair held by an HTTP client to permit a stateful session with an HTTP server.
HttpURLConnection	An URLConnection for HTTP (RFC 2616) used to send and receive data over the web.
IDN	Converts internationalized domain names between Unicode and the ASCII Compatible Encoding (ACE) representation.

InetAddress	An Internet Protocol (IP) address.
InetSocketAddress	This class represents the address of a socket endpoint described by a IP address and a port number.
InterfaceAddress	Identifies one of a network interface's addresses.
JarURLConnection	This class establishes a connection to a jar: URL using the JAR protocol.

SocketImpl	This class is the base of all streaming socket implementation classes.
SocketPermission	Legacy security code; do not use.
SocketUtils
URI	A Uniform Resource Identifier that identifies an abstract or physical resource, as specified by RFC 2396.
URL	A Uniform Resource Locator that identifies the location of an Internet resource as specified by RFC 1738.
URLClassLoader	This class loader is responsible for loading classes and resources from a list of URLs which can refer to either directories or JAR files.
URLConnection	A connection to a URL for reading or writing.
URLDecoder	This class is used to decode a string which is encoded in the application/x-www-form-urlencoded MIME content type.
URLEncoder	This class is used to encode a string using the format required by application/x-www-form-urlencoded MIME content type.
URLStreamHandler	The abstract class URLStreamHandler is the base for all classes which can handle the communication with a URL object over a particular protocol type.

Enum Summary

Enum	Description
Authenticator.RequestorType	Enumeration class for the origin of the authentication request.
Proxy.Type	Enum class for the proxy type.

Exception Summary

Exception	Description
BindException	A BindException is thrown when a process cannot bind a local address/port, either because it is already bound or reserved by the OS.
ConnectException	A ConnectException is thrown if a connection cannot be established to a remote host on a specific port.
HttpRetryException	If a HTTP request has to be retried, this exception will be thrown if the request cannot be retried automatically.
MalformedURLException	This exception is thrown when a program attempts to create an URL from an incorrect specification.
NoRouteToHostException	The NoRouteToHostException will be thrown while attempting to connect to a remote host but the host cannot be reached for instance because of a badly configured router or a blocking firewall.
PortUnreachableException	This PortUnreachableException will be thrown if an ICMP_Port_Unreachable message has been received.
ProtocolException	Signals that either a connection attempt to a socket of the wrong type, the application of an unsupported operation or that a general error in the underlying protocol has occurred.
SocketException	This SocketException may be thrown during socket creation or setting options, and is the superclass of all other socket related exceptions.
SocketTimeoutException	This exception is thrown when a timeout expired on a socket read or accept operation.
UnknownHostException	Thrown when a hostname can not be resolved.
UnknownServiceException	Is thrown if no appropriate ContentHandler could be found for a particular service requested by the URL connection.
URISyntaxException	A URISyntaxException will be thrown if some information could not be parsed while creating a URI.
