Java——获取n个工作日后的日期（这里只除去周末）

 	public static void main(String[] args) throws ParseException {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        Date currDay = sdf.parse("2021-09-7");
        System.out.println(getWorkDay(currDay, 30));
    }

    public static Date getWorkDay(Date startDate, int workDay) {
        Calendar c1 = Calendar.getInstance();
        c1.setTime(startDate);
        for (int i = 0; i < workDay; i++) {
            c1.set(Calendar.DATE, c1.get(Calendar.DATE) + 1);
            if (Calendar.SATURDAY == c1.get(Calendar.DAY_OF_WEEK) 
            	|| Calendar.SUNDAY == c1.get(Calendar.DAY_OF_WEEK)) {
                workDay++;
                continue;
            }
        }
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
        System.out.println(df.format(c1.getTime()));
        return c1.getTime();
    }
