28.16 java.net.Socket (JDK 1.0)

This class implements a socket for interprocess communication over the network. The constructor methods create the socket and connect it to the specified host and port. You may also optionally specify whether communication through the socket should be based on an underlying reliable connection-based stream protocol, or on an underlying unreliable (but faster) datagram protocol. A stream protocol is the default.

Once the socket is created, getInputStream() and getOutputStream() return InputStream and OutputStream objects that you can use just as you would for file input and output. getInetAddress() and getPort() return the address and port that the socket is connected to. getLocalPort() returns the local port that the socket is using.

public class Socket extends Object {
    // Public Constructors
            public Socket(String host, int port) throws UnknownHostException, IOException;
            public Socket(InetAddress address, int port) throws IOException;
        1.1public Socket(String host, int port, InetAddress localAddr, int localPort) throws IOException;

        #   public Socket(String host, int port, boolean stream) throws IOException;
        #   public Socket(InetAddress host, int port, boolean stream) throws IOException;
