Question

Friends I am getting two inputs from the user

1.InitDate from DatePicker
2.Difference in between two dates (numberOfDates)

I need to calculate the FinalDate such that

FinalDate=InitDate+numberOfDates

What I have done till now

private void CalcLastDate(int days) 
        {

long millis=days*24*60*60;

            Calendar c = Calendar.getInstance();

            c.set(settingsFromDate.getYear(), settingsFromDate.getMonth(), settingsFromDate.getDayOfMonth());
            long initDate = c.getTimeInMillis();

            long longFinalDate=initDate+millis;

}

Answer 1

Try this:

Calendar cal = Calendar.getInstance();
cal.setTime(initDate); //initDate must be of java.util.Date
cal.add(Calendar.DAY_OF_MONTH, numberOfDates);

You can get the your final date with:

Date finalDate = cal.getTime();

And you don’t have to use a third party api.
