Question

Code :

DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd");
try {
    date1 = df1.parse(currentDate);
    System.out
            .println("============my formated date====================" + date1.toString());
    Calendar cal = Calendar.getInstance();
    cal.setTime(date1);
    cal.add(Calendar.DATE, 10); // add 10 days

    date1 = cal.getTime();

    System.out.println("==============added date==============" + date1.toString());

I have created one common function for convert date format. You have to pass old Date format, new date format and date.

public static String convertDateFormat(String oldFormat, String newFormat, String inputDate)
    {
        DateFormat theDateFormat = new SimpleDateFormat(oldFormat);
        Date date = null;

        try
        {
            date = theDateFormat.parse(inputDate);
        }
        catch (ParseException parseException)
        {
            // Date is invalid. Do what you want.
        }
        catch (Exception exception)
        {
            // Generic catch. Do what you want.
        }

        theDateFormat = new SimpleDateFormat(newFormat);
        return theDateFormat.format(date).toString();
    }

// Call funcation

String convertedDate = convertDateFormat("EEEE MMM dd,yyyy","yyyy-MM-dd",dateToConvert);
