import java.io.*;
import java.net.*;
import java.util.*;

public class URLdata {
    public static void main(String[] args) {
       try {
          URL url = new URL( args[0] );
          InputStream is = url.openStream();
          InputStreamReader isr = new InputStreamReader( is );
          BufferedReader in = new BufferedReader( isr );
          System.out.println( "----------------------------------------" );
          System.out.println( args[0] );
          System.out.println( "----------------------------------------" );
          String line;
          for( int i=0; i<15; i++ ){
             if( (line = in.readLine()) == null){ break; }
             System.out.println ( line );
       }  }
       catch (Exception e) {
          System.out.println( "error" );
       }
