| 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 |
CacheResponse is used for getting resource data from the installed
ResponseCache. |
| 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. |
| 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. |
| HttpURLConnection |
This abstract subclass of URLConnection defines methods for managing
HTTP connection according to the description given by RFC 2068. |
| Inet4Address |
This class represents a 32 bit long IPv4 address. |
| Inet6Address |
This class represents a 128 bit long IPv6 address. |
| InetAddress |
An Internet Protocol (IP) address. |
| InetSocketAddress |
This class represents a socket endpoint described by a IP address and a port
number. |
| JarURLConnection |
This class establishes a connection to a jar: URL using the JAR protocol. |
| MulticastSocket |
This class implements a multicast socket for sending and receiving IP
multicast datagram packets. |
| NetPermission |
This class represents permissions to configure the access to network
resources. |
| NetworkInterface |
This class is used to represent a network interface of the local device. |
| PasswordAuthentication |
This immutable class is a data structure that encapsulates username and
password which is used by the Authenticator class. |
| Proxy |
This class represents proxy server settings. |
| ProxySelector |
Selects an applicable proxy server when connecting to a resource specified by
a URL. |
| ResponseCache |
This class is an implementation of URLConnection caches intended
primarily for the according stream handler implementations. |
| SecureCacheResponse |
A secure cache response represents data which is originally retrieved over a
secure connection. |
| ServerSocket |
This class represents a server-side socket that waits for incoming client
connections. |
| Socket |
Provides a client-side TCP socket. |
| SocketAddress |
This abstract class represents a protocol-independent base for
socket-endpoint representing classes. |
| SocketImpl |
This class is the base of all streaming socket implementation classes. |
| SocketPermission |
Regulates the access to network operations available through sockets through
permissions. |
| URI |
This class represents an instance of a URI as defined by RFC 2396. |
| URL |
A URL instance specifies the location of a resource on the internet 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 |
Concrete implementations of the abstract URLConnection class provide
a communication link to a URL for exchanging data with a specific protocol
type. |
| 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. |
