java获取指定月份的工作日(只去除周六日，没有去除节假日)

	private static int getWorkDays(int theYear, int theMonth) {
		// 计算指定月有多少工作日
		int workDays = 0;
		Calendar cal = Calendar.getInstance();
		cal.set(theYear, theMonth - 1, 1);// 从每月1号开始
		int days = cal.getActualMaximum(Calendar.DAY_OF_MONTH);
		for (int i = 0; i < days; i++) {
			int day = cal.get(Calendar.DAY_OF_WEEK);
			if (!(day == Calendar.SUNDAY || day == Calendar.SATURDAY)) {
				workDays++;
			}
			cal.add(Calendar.DATE, 1);
		}
		return workDays;
	}
