Though I agree with scubabbl, here is a version without an inner while.

int year = 2008;
for (int m = Calendar.JANUARY; m <= Calendar.DECEMBER; m++) {
    Calendar cal = new GregorianCalendar(year, m, 1);
    cal.set(Calendar.DAY_OF_MONTH, cal.getActualMaximum(Calendar.DAY_OF_MONTH));
    int diff = Calendar.FRIDAY - cal.get(Calendar.DAY_OF_WEEK);
    if (diff > 0) {
        diff -= 7;
    }
    cal.add(Calendar.DAY_OF_MONTH, diff);
    System.out.println(cal.getTime());
}
