Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -2);
Date todayMinusTwo = cal.getTime();

SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd");
Date d0 = null;
try {
   d0 = fmt.parse(date0);
} catch (ParseException ex) {

if (d0.before(todayMinusTwo))
   System.out.println("Before today - 2 days");
else if (d0.after(todayMinusTwo))
   System.out.println("After today - 2 days");
