Description
Interface Summary | |
ContentHandlerFactory | This interface defines a factory for content handlers. |
DatagramSocketImplFactory | This interface defines a factory for datagram socket implementations. |
FileNameMap | A simple interface which provides a mechanism to map between a file name and a MIME type string. |
SocketOptions | Interface of methods to get/set socket options. |
URLStreamHandlerFactory | This interface defines a factory for URL stream
protocol handlers. |
Class Summary | |
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. |
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. |
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. |
SocketAddress | This class represents a Socket Address with no protocol attachment. |
SocketPermission | This class represents access to a network via sockets. |
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. |
URLStreamHandler | The abstract class URLStreamHandler is the common
superclass for all stream protocol handlers. |
Exception Summary | |
BindException | Signals that an error occurred while attempting to bind a socket to a local address and port. |
MalformedURLException | Thrown to indicate that a malformed URL has occurred. |
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. |
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.
