How to subtract N working days from the current date in Java?

Problem Description :

Write a program in Java that subtracts N working days from the current date and prints new date with proper validations.

Concept :

There are 5 working days per week (Monday, Tuesday, Wednesday, Thursday, Friday). Here in a loop we are subtracting 1 from the current date and checking day of that date. If it is Sunday or Saturday then we are doing increment to the value of N because we are interested in working days.
  • We need to do subtraction from current date using add() method of Calendar class that accepts DAY_OF_MONTH constant and number of days that you want to subtract in negative format.
  • For getting day, we need to use DAY_OF_WEEK constant of Calendar class.

   int orignalLimit = limit;
   // Create Calendar class instance
   Calendar calendar = Calendar.getInstance();
   System.out.println("Current Date : " + calendar.getTime());
   for (int i = 1; i <= limit; i++) {
    // Subtracting 1 day from calendar.
    calendar.add(Calendar.DAY_OF_MONTH, -1);
     * calendar.get(Calendar.DAY_OF_WEEK) = 1 (Sunday)
     * calendar.get(Calendar.DAY_OF_WEEK) = 7 (Saturday)
     * If day is either Sunday or Saturday then it is non working
     * day so Increasing the limit to compensate working days.
    if ( calendar.get(Calendar.DAY_OF_WEEK) == 1 || calendar.get(Calendar.DAY_OF_WEEK) == 7) {
   System.out.println("Before " + orignalLimit + " working day/s Date : " + calendar.getTime());
  } finally {
   if (input != null) {
