Question

I need to get the date based on the following condition,

From the current date, If the user selects only date(1-31), must subtract it from the current date and get the new date.

If the user selects weeks(1-53) then we have to remove the selected no’of weeks from the current dates no’of weeks and get a new date.

If the user selects only months(1-12) then we have to delete the selected number of months from the current date months and get a new date.
Sample code for date checking..

Calendar today=Calendar.getInstance();  
int month=today.MONTH;  

int year=today.YEAR;  
today.clear();  
today.set(year, month,dateOfMonth);
date=today.getTime();

Any Logic is highly appreciated.
Thanks in Advance.

Answer 1

java.util.Calendar cal = java.util.Calendar.getInstance();
cal.setTime(currentDate);
if (inDays) {
  cal.add(Calendar.DATE, -n);
} else if (inWeeks) {
  cal.add(Calendar.WEEK_OF_YEAR, -n);
} else if (inMonths) {
  cal.add(Calendar.MONTH, -n);
}
