Java date Conversion issue having input date as String Oct 2014

Question

I need to implement the logic whether input date such as SEP 2014, OCT 2014 , NOV 2014 etc is current month or not. I have written below logic for checking whether a selected week is a current week or not using below method but not able to implement for current month

public static boolean isCurrentWeek(Date date, Date dateStart, Date dateEnd)

 {

    if (date != null && dateStart != null && dateEnd != null) {


        if(date.equals(dateStart) || date.equals(dateEnd) ){


            return true;


        }else if (date.after(dateStart) && date.before(dateEnd)) {


            return true;


        }


        else {


            return false;

        }

    }
    return false;
}

You have code for current week, and you're trying to figure out a current month version, what have you tried so far? Post *that* code. — rolfl, Oct 03 '14 at 14:05

Try Apache Commons for this:

DateUtils.truncatedEquals( date, new Date(), Calendar.MONTH );

It returns true if the two date is in the same month.

EDIT

Maybe this:

public static boolean isInCurrentMonth(String inputDateString) {
    SimpleDateFormat sdf = new SimpleDateFormat("MMM yyyy", Locale.ENGLISH);
    try {
        Date inputDate = sdf.parse(inputDateString);
        return DateUtils.truncatedEquals(new Date(), inputDate, Calendar.MONTH);
    } catch (ParseException e) {
        // error handling
    }
}

I think you can solve your problem with code similar to this one:

String target = "Oct 2000";
DateFormat df = new SimpleDateFormat("MMM yyyy", Locale.ENGLISH);
try{
  Date date = df.parse(target);
  Calendar calendar = Calendar.getInstance();
  Calendar targetCalendar = Calendar.getInstance();
  targetCalendar.setTime(date);
  System.out.println(targetCalendar.get(Calendar.MONTH) == calendar.get(Calendar.MONTH));
 } catch (ParseException e){
 }

String target is your input like "Sep 2014". This string is parsed to a Date and then used to set the time in a Calendar object. The second Calendar contains the current time. The check if boths calenders match on their month is done is the System.out.println call.

Stefan, your code is checking only month but not year for e.g if i pass String target = "Oct 2000" and current month is OCT 2014 its will return true. It should compare the year as well – feroz siddiqui Oct 03 '14 at 14:38
I have modified the your as below and its working fine public static boolean isCurrentMonth(String dateStart) throws ParseException{ DateFormat df = new SimpleDateFormat("MMM yyyy", Locale.ENGLISH); Date date = df.parse(dateStart); Calendar calendar = Calendar.getInstance(); Calendar targetCalendar = Calendar.getInstance(); targetCalendar.setTime(date); return (targetCalendar.get(Calendar.MONTH) == calendar.get(Calendar.MONTH) && targetCalendar.get(Calendar.YEAR) == calendar.get(Calendar.YEAR)); } – feroz siddiqui Oct 03 '14 at 14:41
In your question you are asking only for a match on the month (you wrote: "is current month or not."). As you already know, the code can be easily extended to check also for the year :) So, I you think this solutions works for you, please vote it up. – Stefan Freitag Oct 03 '14 at 14:48
