How to subtract two days from a date in Java?

Question

    String dateSample = "2016-09-30 21:59:22.2500000";

    String oldFormat = "yyyy-MM-dd HH:mm:ss";
    String newFormat = "MM-dd-yyyy";

    SimpleDateFormat sdf1 = new SimpleDateFormat(oldFormat);
    SimpleDateFormat sdf2 = new SimpleDateFormat(newFormat);

    sdf2.format(sdf1.parse(dateSample));

From this, I got 09-30-2016 But, I want the result 09-28-2016 How to do it?

If you put Sep 30th in, why would you expect it to return Sep 28th? I assume you are asking how to subtract two days from the Date? — Peter Lawrey, Oct 06 '16 at 11:27
I suggest you use JSR-310 DataTiIme library added in Java 8 (with a back port to Java 6) — Peter Lawrey, Oct 06 '16 at 11:28

Calendar cal = GregorianCalendar.getInstance();
cal.setTime( sdf1.parse(dateSample));
cal.add( GregorianCalendar.DAY_OF_MONTH, -2); // date manipulation
System.out.println(sdf2.format(cal.getTime()));

Hope I helped

FYI, these notoriously troublesome classes are now legacy, supplanted by the java.time classes. – Basil Bourque Oct 06 '16 at 17:58
