In the following code shows how to use DatagramSocket.isClosed() method.
import java.net.DatagramPacket; import java.net.DatagramSocket; import java.net.InetAddress; // www . j av a2 s. co m public class Main { public static void main(String args[]) { try { InetAddress ia = InetAddress.getByName("www.java2s.com"); DatagramSocket ds = new DatagramSocket(); byte buffer[] = "hello".getBytes(); DatagramPacket dp = new DatagramPacket(buffer, buffer.length, ia, 80); ds.send(dp); System.out.println(ds.isClosed()); } catch (Exception e) { e.printStackTrace(); } } }
The code above generates the following result.
