Answer 1

不太清楚Scanner的用法，我用BufferedReader到是可以读出数据的import java.net.*;
import java.io.*;public class Main 
{
    public static void main(String[] args) throws Exception
    {
        URL url=new URL("http://www.mldnjava.cn/index.html");
        InputStream input=url.openStream();
        BufferedReader in = new BufferedReader(new InputStreamReader(input));
        String str;
        while ((str = in.readLine()) != null)
         System.out.println(str);
    }
}

Answer 2

Exception in thread "main" java.net.SocketException: Software caused connection abort: recv failed从以上的错误信息来看，是Socket获取不到输入流。
