JAVA date difference in years months and days

Here I explain how to get date difference in years, months, days and years, months, weeks, days.

Libraries used:
 joda-time-1.1.jar

package codsstore;


import java.text.ParseException;
import java.text.SimpleDateFormat;

import java.util.Date;
import java.util.logging.Level;
import java.util.logging.Logger;

import org.joda.time.DateTime;
import org.joda.time.Period;
import org.joda.time.format.PeriodFormatter;
import org.joda.time.format.PeriodFormatterBuilder;

        try {

            Date dateFrom = dateFormat.parse("2010-11-11");
            Date dateTo = dateFormat.parse("2011-12-19");

            String dateDiff = getDateDifference(dateFrom, dateTo);
            String dateDiff2 = getDateDifference2(dateFrom, dateTo);

            System.out.println(dateDiff);
            System.out.println(dateDiff2);


        } catch (ParseException ex) {
            Logger.getLogger(DateDiff.class.getName()).log(Level.SEVERE, null, ex);

    public static String getDateDifference(Date dateFrom, Date dateTo) {

        String diff = "";

    public static String getDateDifference2(Date dateFrom, Date dateTo) {

        String diff = "";
        int days = 0;
        DateTime dateTimeFrom = new DateTime(dateFrom);
        DateTime dateTimeTo = new DateTime(dateTo);

        Period period = new Period(dateTimeFrom, dateTimeTo);

        PeriodFormatter formatter = new PeriodFormatterBuilder()
                .appendYears().appendSuffix(" year "," years ")
                .appendMonths().appendSuffix(" month "," months ")
               //.appendWeeks().appendSuffix(" week "," weeks ")

                .printZeroNever()
                .toFormatter();

        diff = formatter.print(period);
        days = period.getDays() + period.getWeeks() * 7;

        if(days  > 0){
            diff += days + ((days==1) ? " day ":" days ");
        }

        if(period.getYears()==0 && period.getMonths()==0 && days == 0){
             diff = "0 days";
        }

        return diff;

    }

}

Output:
1 year 1 month 1 week 1 day
1 year 1 month 8 days
