get last friday of month in java using -'java,date,calendar'

get last friday of month in java  using -'java,date,calendar'

I am working on a project where the requirement is to have a date calculated as being the last Friday of a given month.  I think I have a solution that only uses standard Java, but I was wondering if anyone knew of anything more concise or efficient. Below is what I tested with for this year:

    for (int month = 0; month < 13; month++) {
        GregorianCalendar d = new GregorianCalendar();
        d.set(d.MONTH, month);
        System.out.println("Last Week of Month in " + d.getDisplayName(d.MONTH, Calendar.LONG, Locale.ENGLISH) + ": " + d.getLeastMaximum(d.WEEK_OF_MONTH));
        d.set(d.DAY_OF_WEEK, d.FRIDAY);
        d.set(d.WEEK_OF_MONTH, d.getActualMaximum(d.WEEK_OF_MONTH));
        while (d.get(d.MONTH) > month || d.get(d.MONTH) < month) {
            d.add(d.WEEK_OF_MONTH, -1);
        Date dt = d.getTime();
        System.out.println("Last Friday of Last Week in  " + d.getDisplayName(d.MONTH, Calendar.LONG, Locale.ENGLISH) + ": " + dt.toString());
