问题
I am getting incorrect results whatever I do. Could anyone give me some advise please :).
Here is the code of my program the is responsible for getting the time between two dates.
I am getting a result but the problem is that it is incorrect and I have having trouble finding the problem.
I have to Joda library in my project.
if (timerightnow.isSelected()) {
DateFormat getdate = new SimpleDateFormat("dd/MM/yy HH:mm:ss");
Date getdate1 = new Date();
String datenow = getdate1.toString();
String monthnow = datenow.substring(4, 7);
String daynow = datenow.substring(8,10);
String hournow = datenow.substring(11,19);
String yearnow = datenow.substring(25, 29);
if (monthnow.equalsIgnoreCase("jan"))
monthnow = "01";
if (monthnow.equalsIgnoreCase("feb"))
monthnow = "02";
if (monthnow.equalsIgnoreCase("mar"))
monthnow = "03";
if (monthnow.equalsIgnoreCase("apr"))
monthnow = "04";
if (monthnow.equalsIgnoreCase("may"))
monthnow = "05";
if (monthnow.equalsIgnoreCase("jun"))
monthnow = "06";
if (monthnow.equalsIgnoreCase("jul"))
monthnow = "07";
if (monthnow.equalsIgnoreCase("agu"))
monthnow = "08";
if (monthnow.equalsIgnoreCase("sep"))
monthnow = "09";
if (monthnow.equalsIgnoreCase("oct"))
monthnow = "10";
if (monthnow.equalsIgnoreCase("nov"))
monthnow = "11";
if (monthnow.equalsIgnoreCase("dec"))
monthnow = "12";
String timenow = monthnow + "/" + daynow + "/" + yearnow + " " + hournow;
String timetotext = timeto.getText();
SimpleDateFormat date = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Date datestart = null;
Date dateend = null;
try {
datestart = date.parse(timenow);
dateend = date.parse(timetotext);
DateTime datestartdaytime = new DateTime(datestart);
DateTime dateenddaytime = new DateTime(dateend);
JOptionPane.showMessageDialog(null, datestartdaytime + "\n" + dateenddaytime);
int monthoutput = Months.monthsBetween(datestartdaytime, dateenddaytime).getMonths();
int daysoutput = Days.daysBetween(datestartdaytime, datestartdaytime).getDays() % 30;
int hoursoutput = Hours.hoursBetween(datestartdaytime, datestartdaytime).getHours() % 24;
int minutsoutput = Minutes.minutesBetween(datestartdaytime, dateenddaytime).getMinutes() % 60;
int secondsoutput = Seconds.secondsBetween(datestartdaytime, dateenddaytime).getSeconds() % 60;
answer.setText(monthoutput + "Months" + daysoutput + "Days" + hoursoutput + "Hours" + minutsoutput + "Minutes" + secondsoutput + "Seconds");
Thanks a lot :)

Your bug is in these two lines:
int daysoutput = Days.daysBetween(datestartdaytime, datestartdaytime).getDays() % 30;
int hoursoutput = Hours.hoursBetween(datestartdaytime, datestartdaytime).getHours() % 24;
You intended to use dateenddaytime
as the second argument:
int daysoutput = Days.daysBetween(datestartdaytime, dateenddaytime).getDays() % 30;
int hoursoutput = Hours.hoursBetween(datestartdaytime, dateenddaytime).getHours() % 24;
