Ich erhalte eine Ausnahme, wenn ich diesen Code ausführe. Warum?
Ausnahme im Thread "main" java.net.ConnectException: Zeitüberschreitung bei der Verbindung: connect
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
public class MainClass {
public static void main(String[] args) throws Exception {
System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
URL url = new URL("https://www.verisign.com/");
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
in.close();
}
}
