date - How to get the current time in YYYY-MM-DD HH:MI:Sec.Millisecond format in Java?

The code below gives me the current time. But it does not tell anything about milliseconds.

public static String getCurrentTimeStamp() {
    SimpleDateFormat sdfDate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//dd/MM/yyyy
    Date now = new Date();
    String strDate = sdfDate.format(now);
    return strDate;
}

I get date in the format 2009-09-22 16:47:08 (YYYY-MM-DD HH:MI:Sec).

But I want to retrieve the current time in the format 2009-09-22 16:47:08.128 ((YYYY-MM-DD HH:MI:Sec.Ms)- where 128 tells the millisecond.

SimpleTextFormat will work fine. Here the lowest unit of time is second, but how do I get millisecond as well?

Answer

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
