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 have a date in the format YYYY-MM-DD HH:MM:SS (2009-09-22 16:47:08).

But I want to retrieve the current time in the format YYYY-MM-DD HH:MM:SS.MS (2009-09-22 16:47:08.128, where 128 are the milliseconds).

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

Solution 1:

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

Solution 2:

A Java one liner

public String getCurrentTimeStamp() {
    return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(new Date());
}

in JDK8 style

public String getCurrentLocalDateTimeStamp() {
    return LocalDateTime.now()
       .format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS"));
}
