calendar - Java: getting current Day of the Week value

At the moment, I'm creating a java schedule app and I was wondering how to find the current day of the week while using the Calendar class to get the first day of the week.

Here is the method I'm using in a class in order to set up a week schedule

public static String getSunday() {
    SimpleDateFormat d = new SimpleDateFormat(dayDate);
    Calendar specific = cal;
    specific.add(Calendar.DAY_OF_YEAR, (cal.getFirstDayOfWeek() - ??));
    return d.format(specific.getTime());
}

You can get the current day of the week by calling get() with Calendar.DAY_OF_WEEK

public int getTodaysDayOfWeek() {
  final Calendar c = Calendar.getInstance();
  return c.get(Calendar.DAY_OF_WEEK);
}

Also, while I'm not sure I understand exactly what you're trying to do, it looks fishy to me. (What's cal for example?)
