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

    cal.setTime(date1);
    cal.add(Calendar.DATE, 10); // add 10 days

    date1 = cal.getTime();

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

Answer 1

You must parse it into the date of your current format before format it to another date

DateFormat df_parse = new SimpleDateFormat("EEEE MMM dd,yyyy");
Date date_parse = df_parse.format(currentDate);
DateFormat df1 = new SimpleDateFormat("yyyy-MM-dd");
date1 = df1.parse(date_parse);
