public class EchoClient { private Socket socket; public EchoClient(String url,int port){ try { socket=new Socket(url, port); System.out.println("Client:connected to"+url+":"+port); } catch (Exception e) { e.printStackTrace(); System.exit(1); } } public static void main(String[] args) { EchoClient client =new EchoClient("url", 10001); client.start(); } }
main函数里这个url该怎么找啊,谢谢了
