ClassDescriptionThe class Authenticator represents an object that knows how to obtain authentication for a network connection.The type of the entity requesting authentication.Represents channels for storing resources in the ResponseCache.Represent channels for retrieving resources from the ResponseCache.The abstract class
ContentHandler
is the superclass of all classes that read anObject
from aURLConnection
.This interface defines a factory for content handlers.A CookieHandler object provides a callback mechanism to hook up a HTTP state management policy implementation into the HTTP protocol handler.CookiePolicy implementations decide which cookies should be accepted and which should be rejected.A CookieStore object represents a storage for cookie.This class represents a datagram packet.This class represents a socket for sending and receiving datagram packets.Abstract datagram and multicast socket implementation base class.This interface defines a factory for datagram socket implementations.A simple interface which provides a mechanism to map between a file name and a MIME type string.An HttpCookie object represents an HTTP cookie, which carries state information between server and user agent.This class represents an Internet Protocol version 4 (IPv4) address.This class represents an Internet Protocol version 6 (IPv6) address.This class represents an Internet Protocol (IP) address.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.This class represents a Network Interface address.Thrown to indicate that a malformed URL has occurred.This class represents a Network Interface made up of a name, and a list of IP addresses assigned to this interface.The class PasswordAuthentication is a data holder that is used by Authenticator.Thrown to indicate that there is an error in the underlying protocol, such as a TCP error.Represents a family of communication protocols.This class represents a proxy setting, typically a type (http, socks) and a socket address.Represents the proxy type.Selects the proxy server to use, if any, when connecting to the network resource referenced by a URL.Represents implementations of URLConnection caches.This class implements server sockets.This class implements client sockets (also called just "sockets").This class represents a Socket Address with no protocol attachment.Thrown to indicate that there is an error creating or accessing a Socket.The abstract classSocketImpl
