Java实现“三天打渔两天晒网”

如题，上代码！

  
    @Test
    public void Test03() throws ParseException {
        String s1 = "1990-01-01";
        String s2 = "2020-09-08";

        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        //解析   字符串--->日期
        Date date = sdf.parse(s1);
        Date date1 = sdf.parse(s2);

        long time1 = date1.getTime();
        long time = date.getTime();

        long timevalue = time1 - time;
        System.out.println("总天数的毫秒数timevalue = " + timevalue);

        int day = (int) (timevalue / (1000 * 60 * 60 * 24));
        System.out.println("总天数day = " + day);

        int workDay = day % 5;
        System.out.println("workDay = " + workDay);
        if (workDay > 0 && workDay < 4) {
            System.out.println(s2 + " 这一天，渔夫在打渔");
        } else
            System.out.println(s2 + " 这一天，渔夫在晒网");
    }

实现结果：
