datetime - How to get every day except weekend or Saturday or Sunday between two dates in java?

Question

hi all how to generate dates if the start date and end date are provided in java?

like the following :

Ex : if the start date is 15-04-2012 and end date is 15-06-2012 having this i want dates to be like the following and the list should omit saturday and sunday

1.15-04-2012, 2.16-04-2012, 3.17-04-2012, . . . . . . 15-06-2012

I have done like the following but it will generate for one month if the date range is of same month. `

public static ConcurrentHashMap<String, String> getWorkingDaysMap(int year, int month, int day){
        int totalworkingdays=0,noofdays=0;
        String nameofday = "";
        ConcurrentHashMap<String,String> workingDaysMap = new ConcurrentHashMap<String,String>();
        Map<String,String> holyDayMap = new LinkedHashMap<String,String>();
        noofdays = findNoOfDays(year,month,day);

        for (int i = 1; i <= noofdays; i++) {
            Date date = (new GregorianCalendar(year,month - 1, i)).getTime(); // year,month,day
            SimpleDateFormat f = new SimpleDateFormat("EEEE");
            nameofday = f.format(date);

            String daystr="";
            String monthstr="";

            if(i<10)daystr="0";
            if(month<10)monthstr="0";

            String formatedDate = daystr+i+"/"+monthstr+month+"/"+year;

            if(!(nameofday.equals("Saturday") || nameofday.equals("Sunday"))){
                workingDaysMap.put(formatedDate,formatedDate);
                totalworkingdays++;
            }
        }

        return workingDaysMap;
    }

So please do advice me how to go about.

Answer 1

int noOfDaysBetween = 5;
Calendar cal  = Calendar.getInstance();
cal.setTime(startDate);

for(int index = 0 ; index < noOfDaysBetween; index++){
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK);
    if( dayOfWeek!=Calendar.SUNDAY && dayOfWeek!=Calendar.SATURDAY) {
        System.out.println(cal.getTime());
    }
    cal.add(Calendar.DATE, 1);
}
