Server request for a table in Java

Question

I am trying to ask this server for a table, but I'm not sure how to do this. Basically I am trying to get the Eclipse program to print something like this when the program starts:

<tr><td>
 <pre>

                       <b>2011 Phases of the Moon</b>
                            Universal Time

        New Moon   First Quarter       Full Moon    Last Quarter   

         d  h  m         d  h  m         d  h  m         d  h  m

    Jan  4  9 03    Jan 12 11 31    Jan 19 21 21    Jan 26 12 57
    Feb  3  2 31    Feb 11  7 18    Feb 18  8 36    Feb 24 23 26
    Mar  4 20 46    Mar 12 23 45    Mar 19 18 10    Mar 26 12 07
    Apr  3 14 32    Apr 11 12 05    Apr 18  2 44    Apr 25  2 47
    May  3  6 51    May 10 20 33    May 17 11 09    May 24 18 52
    Jun  1 21 03    Jun  9  2 11    Jun 15 20 14    Jun 23 11 48
    Jul  1  8 54    Jul  8  6 29    Jul 15  6 40    Jul 23  5 02
    Jul 30 18 40    Aug  6 11 08    Aug 13 18 57    Aug 21 21 54
    Aug 29  3 04    Sep  4 17 39    Sep 12  9 27    Sep 20 13 39
    Sep 27 11 09    Oct  4  3 15    Oct 12  2 06    Oct 20  3 30
    Oct 26 19 56    Nov  2 16 38    Nov 10 20 16    Nov 18 15 09
    Nov 25  6 10    Dec  2  9 52    Dec 10 14 36    Dec 18  0 48
    Dec 24 18 06                                               
 </pre>
 </td></tr>

This is what I have so far:

import java.util.Scanner;
import java.io.*;
import java.net.*;
/**
   This program shows the moon phase table for the given year
*/
public class MoonPhaseTable
{  
    public static void main(String[] args) throws IOException
    {  
        Scanner in = new Scanner(System.in); //read year number from user
        System.out.print("Please enter the year (e.g. 1977): ");
        int year = in.nextInt();

        // Build the URL string and open a URLConnection
        // Be sure to set the year on the URL string!!!
        URL moonphase = new URL("http://aa.usno.navy.mil/cgi-bin/aa_moonphases.pl?year=2015/");
        URLConnection mp = moonphase.openConnection();      

        // Get the connection input stream, and make a Scanner for it
        BufferedReader r = new BufferedReader(new InputStreamReader(mp.getInputStream()));

        Scanner s = new Scanner(moonphase.openStream());

        String inputLine;

        boolean printingTable = false;
        while ((inputLine = r.readLine()) !=null) {
                 // Read input lines from the scanner into the String named line.

             if (printingTable) {     
                 // Check if the line contains the </table> end tag -- if seen, turn off printing
                 System.out.print("CONTAINS </table>");
                 s.close(); 
             }
             if (printingTable) {
                 // If inside the Table, print the line.
                 // Optionally clean up any unwanted tags, such as
                 // <pre>, <tr>, <td>, <b> before printing.
                 System.out.print(inputLine);

             }
             if (!printingTable) {
                 // Check if the line contains the <table ...> start tag -- if seen, turn on printing
                 System.out.print(inputLine);
             }
           }
        }

    }

He is currently printing all the source code. I only need the code as shown above. I know that I am not checking the correctness of the table row, but I am not sure how to do this. If anyone has any suggestions, it would be very helpful. I think I should ask the aa.usno.navy.mil server for the moon table, but again .. I'm lost.
