How to check if it’s Saturday/Sunday?

Question

public static void main(String[] args) {
    Calendar c = Calendar.getInstance();
    // Set the calendar to monday of the current week
    c.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY);

    // Print dates of the current week starting on Monday to Friday
    DateFormat df = new SimpleDateFormat("EEE dd/MM/yyyy");
    for (int i = 0; i <= 10; i++) {
        System.out.println(df.format(c.getTime()));
        int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
        if (dayOfWeek == Calendar.FRIDAY) { // If it's Friday so skip to Monday
            c.add(Calendar.DATE, 3);
        } else if (dayOfWeek == Calendar.SATURDAY) { // If it's Saturday skip to Monday
            c.add(Calendar.DATE, 2);
        } else {
            c.add(Calendar.DATE, 1);
        }

        // As Cute as a ZuZu pet.
        //c.add(Calendar.DATE, dayOfWeek > Calendar.THURSDAY ? (9 - dayOfWeek) : 1);
    }
}

If you want to be cute you can replace the if/then/else with

c.add(Calendar.DATE, dayOfWeek > 5 ? (9 - dayOfWeek) : 1);

but I really wanted something easily understood and readable.
