ServerSocket() constructor from ServerSocket has the following syntax.
public ServerSocket() throws IOException
In the following code shows how to use ServerSocket.ServerSocket() constructor.
import java.io.IOException; import java.net.InetSocketAddress; import java.net.ServerSocket; import java.net.Socket; import java.net.SocketTimeoutException; // w w w. j a v a2 s .c o m public class Main extends Thread { private ServerSocket serverSocket; public Main () throws IOException { serverSocket = new ServerSocket(); serverSocket.setSoTimeout(10000); serverSocket.bind(InetSocketAddress.createUnresolved("java2s.com", 8080), 1000); } public void run() { while (true) { try { System.out.println("Waiting for client on port " + serverSocket.getLocalPort() + "..."); Socket client = serverSocket.accept(); System.out.println("Just connected to " + client.getRemoteSocketAddress()); client.close(); } catch (SocketTimeoutException s) { System.out.println("Socket timed out!"); break; } catch (IOException e) { e.printStackTrace(); break; } } } public static void main(String[] args) { try { Thread t = new Main (); t.start(); } catch (IOException e) { e.printStackTrace(); } } }
