TCP的使用 Client的部分
今天我的Client端是這樣寫public static void main(String args[]) throws IOException{
Socket client= new Socket(args, 12345);
System.out.println("Ip : "+args+" Port : 12345");
System.out.println("Resource requirement :< A: "+args+" B: "+args);
System.out.println("Connecting...");
DataOutputStream outToServer = new DataOutputStream(client.getOutputStream());
outToServer.writeBytes(args);
outToServer.writeBytes(args);
InputStream in=client.getInputStream();
BufferedReader buf= new BufferedReader(new InputStreamReader(client.getInputStream()));
System.out.println(buf.readLine());
client.close();
in.close();
outToServer.close();
buf.close();
}
但在commend line中會出現這些錯誤
D:\Java\workspace\B013021032_HW8\src>java Client 5 2 140.117.168.11 12345
Exception in thread "main" java.net.ConnectException: Connection timed out: connect

請問這問題出在哪裡?
