how to get the values from hashmap

[baktha.thalapathy]

 Set<String> dates = new HashSet<String>();
         ArrayList<Integer> l=new ArrayList<Integer>();
         ArrayList<Integer> m=new ArrayList<Integer>();
         
         Map <String, Long> datesAndTotal = new HashMap<String, Long>();
         DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
 while ( rs.next() )
         {

            String gpstime = rs.getString("GpsTime");
            //System.out.println("Time in minutes: " + diffSeconds+ " seconds.");


            if (dates.add(gpstime) )
            {
               //System.out.println(rs.getTimestamp(1));
               Date d2 = rs.getDate(1);
               //System.out.print(d2);
               t2 =   rs.getTimestamp(1);

               count++;
               if (t1 == null )
               {
                  int nano = t2.getSeconds();
                  //System.out.println(nano);
                  System.out.println(nano);
                  System.out.println(t2);
                  System.out.println(count);
               }

               else
               {

                  mill= (t1.getTime() - t2.getTime())/-1;

                  //System.out.println(d1);
                  diffSeconds = mill / 1000;
                  diffMinutes = mill / (60 * 1000);
                  long diffHours = mill / (60 * 60 * 1000);
                  long diffDays = mill / (24 * 60 * 60 * 1000);
                  //System.out.println("\nThe Date Different");
                  //System.out.println("Time in milliseconds: " + mill+ " milliseconds.");
                  System.out.println("GPSTime " +gpstime+ " Time in seconds: " + diffSeconds+ " seconds.");
                  //System.out.println("Time in minutes: " + diffMinutes+ " minutes.");
                  //System.out.println("Time in hours: " + diffHours+ " hours.");
                  //System.out.println("Time in days: " + diffDays+ " days.");


                  totalTimeInMillis = (t2.getTime() - t1.getTime()) / 1000;

                  //System.out.println(totalTimeInMillis);

                   String dateString = df.format(d2);

                  if (datesAndTotal.containsKey(dateString))
                  {
                      m.add((totalTimeInMillis < 80) ? (int) totalTimeInMillis : (int) (totalTimeInMillis % 60));

                      for (int y=0; y<m.size();)
                      {
                      sum+=m.get(y);
                      y++;
                    }
                         // System.out.println(sum);
                      
                      sum+= datesAndTotal.get(dateString)/-1;
                  }
                    

                  datesAndTotal.put(dateString, sum);
             
                
               }
               t1 = t2;
               l.add((diffSeconds < 80) ? (int) diffSeconds : (int) (diffMinutes % 60));
               
            }
         }
         System.out.println(datesAndTotal);

output

{2010-05-12=17575, 2010-05-11=17030, 2010-05-13=31027}

how do i get the values of {}

like this
2010-05-12 17575
2010-05-11 17030
2010-05-13 31027

i need output like
2010-05-11 (17030)->output of 11 th date
17575-17030 (545)->output of 12 th date
31027-17575 (13452)->output of 13th date


how do i change the give code to get above output

please help anybody having idea

Thanks in advance

Take a counter which works like a key for the map and concatenate sum with dateString to make the value.

i couldn't run your code because a lot of classes were missing. here is a small example how to iterate through a hashmap

import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

public class HashMapExample {
	public static void main(String[] args) {
		Map h = new HashMap();
		// Pflege der Aliase
		h.put("john", "f.mueller@test.de");
		h.put("fred", "fk@b-blabla.com");
		h.put("paula", "paula@gmx.de");
		h.put("lisa", "user789@yahoo.com");

		// to get the iterator, you must first get all
		// pairs with entrySet()
		Iterator it = h.entrySet().iterator();
		while (it.hasNext()) {
			// the iterator gives back an object
			// of type Map.Entry, so you must cast
			// the elements with Map.Entry
			Map.Entry entry = (Map.Entry) it.next();
			// your data are in the object entry and you can
			// get the key with getKey() and the value with getValue()
			System.out.println((String) entry.getKey() + " -> "
					+ (String) entry.getValue());
		}
	}
}

so the output is

paula -> paula@gmx.de
fred -> fk@b-blabla.com
john -> f.mueller@test.de
lisa -> user789@yahoo.com

thanks for your reply

i am getting the values like this

2010-05-11 -> 17030
2010-05-12 -> 17575
2010-05-13 -> 31027
2010-05-14 -> 42599
2010-05-15 -> 53155
2010-05-16 -> 62191



now i need take the diff values from
2010-05-11 -> 17030->this is output of 2010-05-11
(2010-05-12 -> 17575)-(2010-05-11 -> 17030)-->545-this is output of 2010-05-12
(2010-05-13 -> 31027)-(2010-05-12 -> 17575)-->13452-this is the output of 2010-05-13
(2010-05-14 -> 42599)-(2010-05-13 -> 31027)-->11572-this is the output of 2010-05-14

i need this type of output which one i need to change to get the above output

thanks in advance

Iterator it = datesAndTotal.entrySet().iterator();
		String prevKey="";
		while (it.hasNext()) {
			Map.Entry entry = (Map.Entry) it.next();
			String presentKey=(String)entry.getKey();
			if(prevKey.length()==0){
				System.out.println(presentKey+"->"+entry.getValue());
			}
			else{
				Long present=(Long)entry.getValue();
				Long prev=datesAndTotal.get(prevKey);
				long result=present-prev;
				System.out.println("("+presentKey+")-("+prevKey+")->"+result);
			}
			prevKey=(String)presentKey;
		}

[baktha.thalapathy]

now i got the exact output

(2010-05-12)-(2010-05-11)->545
(2010-05-13)-(2010-05-12)->13452
(2010-05-14)-(2010-05-13)->11572
(2010-05-15)-(2010-05-14)->10556
(2010-05-16)-(2010-05-15)->9036
