Generate a current datestamp in Java

Date myDate = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd:HH-mm-ss");
String myDateString = sdf.format(myDate);

Date myDate = new Date();
FastDateFormat fdf = FastDateFormat.getInstance("yyyy-MM-dd:HH-mm-ss");
String myDateString = fdf.format(myDate);

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd:HH-mm-ss");
Date yourDate = sdf.parse("2008-09-18:22-03-15");

Date d = new Date();
String formatted = new SimpleDateFormat ("yyyy-MM-dd:HH-mm-ss").format (d);
System.out.println (formatted);

long timestamp = System.currentTimeMillis()

final DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd:hh-mm-ss");

formatter.format(new Date());
