Wie bestätige ich ein timestamp?

Ich bin mir nicht ganz sicher über das format, aber Sie können Sie spielen, um es und können versuchen, so etwas wie dieses

public static bool isTimeStampValid(String inputString)
{ 
    SimpleDateFormat format = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS");
    try{
       format.parse(inputString);
       return true;
    }
    catch(ParseException e)
    {
        return false;
    }
}

EDIT: wenn Sie überprüfen möchten, für die zahlen nach dem erfolgreichen Parsen, die Sie tun könnten,

       format.parse(inputString);
       Pattern p = Pattern.compile("^\\d{4}[-]?\\d{1,2}[-]?\\d{1,2} \\d{1,2}:\\d{1,2}:\\d{1,2}[.]?\\d{1,6}$");
       return p.matcher(inputString).matches();

statt

   format.parse(inputString);
   return true;
