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. |
Inet4Address |
An IPv4 address. |
Inet6Address |
An IPv6 address. |
InetAddress |
An Internet Protocol (IP) address. |
InetSocketAddress |
This class represents 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. |
MulticastSocket |
This class implements a multicast socket for sending and receiving IP
multicast datagram packets. |
NetPermission |
Legacy security code; do not use. |
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 the proxy server to use, if any, when connecting to a given URL. |
ResponseCache |
Caches URLConnection responses. |
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 |
Legacy security code; do not use. |
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. |
