<Socket>

 

 

Socket(String host, int port)

Creates a stream socket and connects it to the specified port number on the named host.

 

getInputStream() Returns an input stream for this socket.

 

getOutputStream()

Returns an output stream for this socket.

 

 

<serverSocket>

 

This class implements server sockets. A server socket waits for requests to come in over the network. It performs some operation based on that request, and then possibly returns a result to the requester.

 

ServerSocket(int port)

Creates a server socket, bound to the specified port.

 

 

public Socket accept()
              throws IOException

Listens for a connection to be made to this socket and accepts it. The method blocks until a connection is made.

A new Socket s is created and, if there is a security manager, the security manager's checkAccept method is called with s.getInetAddress().getHostAddress() and s.getPort() as its arguments to ensure the operation is allowed. This could result in a SecurityException.

Returns:the new Socket

 

ex) serverSocket = new ServerSocket(9999);

Socket socket  = serverSocket.accept();
