Creating a Client Socket

Demo Code



import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;

public class Main {
  public static void main(String[] args) {
    // Create a socket without a timeout
    try {/*from www .  j a v  a2  s  .  c o m*/
      InetAddress addr = InetAddress.getByName("java.sun.com");
      int port = 80;

      // This constructor will block until the connection succeeds
      Socket socket = new Socket(addr, port);
    } catch (UnknownHostException e) {
    } catch (IOException e) {
    }

  }
}

Demo Code


import java.io.IOException;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.SocketTimeoutException;
import java.net.UnknownHostException;

public class Main {
  public static void main(String[] args) {
    // Create a socket with a timeout
    try {/*from w w w . ja v  a  2 s  . co  m*/
      InetAddress addr = InetAddress.getByName("java.sun.com");
      int port = 80;
      SocketAddress sockaddr = new InetSocketAddress(addr, port);

      // Create an unbound socket
      Socket sock = new Socket();

      // This method will block no more than timeoutMs.
      // If the timeout occurs, SocketTimeoutException is thrown.
      int timeoutMs = 2000; // 2 seconds
      sock.connect(sockaddr, timeoutMs);
    } catch (UnknownHostException e) {
    } catch (SocketTimeoutException e) {
    } catch (IOException e) {
    }

  }
