import java.io.IOException;
import java.net.*;
public class JavaSocketGetChannelExample1 {
    public static void main(String[] args) throws IOException {
      Socket socket = new Socket();
      InetAddress inetAddress=InetAddress.getByName(null);
      //the port should be greater or equal to 0, else it will throw an error
        //passing negative port number
        int port=1085;
        //calling the constructor of the SocketAddress class
        SocketAddress socketAddress=new InetSocketAddress(inetAddress, port);
        //binding the  socket with the inetAddress and port number
        socket.bind(socketAddress);
        int timeout=10000;
        //connect() method connects this socket to the server with the given timeout value.
        socket.connect(socketAddress,timeout);
        //getChannel() method returns the channel connected with this socket
        System.out.println("Channel: "+socket.getChannel());
        System.out.println("Inet address: "+socket.getInetAddress());
        System.out.println("Port number: "+socket.getLocalPort());
    }
}

输出

Channel: null
Inet address: localhost/127.0.0.1
Port number: 1085
