java.lang.Object
   |
   +----java.net.Socket
public final class Socket
extends Object
The client Socket class. It uses a SocketImpl to implement the actual socket operations. It is done this way so that you are able to change socket implementations depending on the kind of firewall that is used. You can change socket implementations by setting the SocketImplFactory.

Constructor Index

o Socket(InetAddress, int)
Creates a stream socket and connects it to the specified address on the specified port.
o Socket(InetAddress, int, boolean)
Creates a socket and connects it to the specified address on the specified port.
o Socket(String, int)
Creates a stream socket and connects it to the specified port on the specified host.
o Socket(String, int, boolean)
Creates a socket and connects it to the specified port on the specified host.

Method Index

o close()
Closes the socket.
o getInetAddress()
Gets the address to which the socket is connected.
o getInputStream()
Gets an InputStream for this socket.
o getLocalPort()
Gets the local port to which the socket is connected.
o getOutputStream()
Gets an OutputStream for this socket.
o getPort()
Gets the remote port to which the socket is connected.
o setSocketImplFactory(SocketImplFactory)
Sets the system's client SocketImplFactory.
o toString()
Converts the Socket to a String.

Constructors

o Socket 
  public Socket(String host,
                int port) throws UnknownHostException, IOException
Creates a stream socket and connects it to the specified port on the specified host.
Parameters:
host - the host
port - the port
o Socket 
  public Socket(String host,
                int port,
                boolean stream) throws IOException
Creates a socket and connects it to the specified port on the specified host. The last argument lets you specify whether you want a stream or datagram socket.
Parameters:
host - the specified host
port - the specified port
stream - a boolean indicating whether this is a stream or datagram socket
o Socket 
  public Socket(InetAddress address,
                int port) throws IOException
Creates a stream socket and connects it to the specified address on the specified port.
Parameters:
address - the specified address
port - the specified port
o Socket 
  public Socket(InetAddress address,
                int port,
                boolean stream) throws IOException
Creates a socket and connects it to the specified address on the specified port. The last argument lets you specify whether you want a stream or datagram socket.
Parameters:
address - the specified address
port - the specified port
stream - a boolean indicating whether this is a stream or datagram socket

Methods

o getInetAddress 
  public InetAddress getInetAddress()
Gets the address to which the socket is connected.
o getPort 
  public int getPort()
Gets the remote port to which the socket is connected.
o getLocalPort 
  public int getLocalPort()
Gets the local port to which the socket is connected.
o getInputStream 
  public InputStream getInputStream() throws IOException
Gets an InputStream for this socket.
o getOutputStream 
  public OutputStream getOutputStream() throws IOException
Gets an OutputStream for this socket.
o close 
  public synchronized void close() throws IOException
Closes the socket.
o toString 
  public String toString()
Converts the Socket to a String.
Overrides:
toString in class Object
o setSocketImplFactory 
  public static synchronized void setSocketImplFactory(SocketImplFactory fac) throws IOException
Sets the system's client SocketImplFactory. The factory can be specified only once.
Parameters:
fac - the desired factory
Throws: SocketException
If the factory is already defined.
