语法格式 Seconds Minutes Hours DayofMonth Month DayofWeek Year Seconds Minutes Hours DayofMonth Month...只能用在DayofMonth和DayofWeek两个域中使用。它被用来指定“非明确的值”。因为DayofMonth和 DayofWeek会相互影响，当着两个元素互斥时，应该通过设置一个问号(?)...又如，在DayofWeek使用 MON,WED,FRI，表示星期一、星期三、星期五 L 表示最后(last)，只能用于DayofWeek和DayofMonth域，如果在DayofWeek域使用5L,意味着在最后的一个星期四触发...DayofWeek域使用L，并在L前面加上数字，它表示该月最后一个星期×，例如 6L 就表示一个月的最后一个 星期五 W 只能用于DayofMonth域。...# 字符可用于DayofWeek域。表示“该月第几个周×”，比如"6#3"表示该月第三个周五( 6表示周五，而#3 表示该月第三个)。又如 "2#1" 表示该月第一个周一。

(); assert dayName.equals("SUNDAY"); DayOfWeek day = DayOfWeek.valueOf(dayName); assert day == DayOfWeek.SUNDAY...; 这也可以使用动态枚举类型: Class enumType = DayOfWeek.class; DayOfWeek day = Enum.valueOf(enumType,..."SUNDAY"); assert day == DayOfWeek.SUNDAY; 如果指定的枚举没有具有匹配名称的常量，这两个valueOf()方法都会抛出IllegalArgumentException...Guava库提供了一个helper方法Enums.getIfPresent()，它返回一个可选的 Guava，以消除显式异常处理: DayOfWeek defaultDay = DayOfWeek.SUNDAY...; DayOfWeek day = Enums.getIfPresent(DayOfWeek.class, "INVALID").or(defaultDay); assert day == DayOfWeek.SUNDAY

取到一周中的第几天，但java中一周中的第一天是周日，按照我们的习惯第一天是周一，所以又得做个转换，代码如下： public static int getWeekday(Date date){ int dayOfWeek...= 0; Calendar cal = Calendar.getInstance(); cal.setTime(date); dayOfWeek = cal.get(Calendar.DAY_OF_WEEK...)-1; if (dayOfWeek == 0) { dayOfWeek = 7; } return dayOfWeek; } 农历日期算起来有点麻烦，我就直接找了网上的开源代码...= 0; Calendar cal = Calendar.getInstance(); cal.setTime(date); dayOfWeek = cal.get(Calendar.DAY_OF_WEEK...)-1; if (dayOfWeek == 0) { dayOfWeek = 7; } return dayOfWeek; } final static String[] weekHoliday
getDayOfWeek() DayOfWeek是一个枚举，有七个取值，从DayOfWeek.MONDAY到DayOfWeek.SUNDAY。...(DayOfWeek.TUESDAY)).atTime(10, 0); 这个next方法是怎么实现的呢？...看代码： public static TemporalAdjuster next(DayOfWeek dayOfWeek) { int dowValue = dayOfWeek.getValue...dayOfWeek) public static TemporalAdjuster lastInMonth(DayOfWeek dayOfWeek) public static TemporalAdjuster...previous(DayOfWeek dayOfWeek) public static TemporalAdjuster nextOrSame(DayOfWeek dayOfWeek) 这些方法的含义比较直观
dayOfWeek) {} // 校准到对应月份的最后一个星期N public static TemporalAdjuster lastInMonth(DayOfWeek dayOfWeek...dayOfWeek) {} // 校准到下一个星期N public static TemporalAdjuster next(DayOfWeek dayOfWeek) {}...// 校准到下一个星期N，如果当前日期时间对象满足dayOfWeek，则返回自身 public static TemporalAdjuster nextOrSame(DayOfWeek dayOfWeek...) {} // 校准到上一个星期N public static TemporalAdjuster previous(DayOfWeek dayOfWeek) {} // 校准到上一个星期...N，如果当前日期时间对象满足dayOfWeek，则返回自身 public static TemporalAdjuster nextOrSame(DayOfWeek dayOfWeek) {}
= calendarFirstDay.get(Calendar.DAY_OF_WEEK); if (dayOfWeek == Calendar.SUNDAY) {...dayOfWeek = 7; } else { dayOfWeek = dayOfWeek - 1; } daysOfFirstWeek...= MAX_COLUMN - dayOfWeek + 1; } private void createWaitBackground(int topX, int topY) {...= calendar.get(Calendar.DAY_OF_WEEK); if (dayOfWeek == Calendar.SUNDAY) { dayOfWeek...= 6; } else { dayOfWeek = dayOfWeek - 2; } return dayOfWeek;
