Java檢查今天的日期是兩週週二

Question

我有幾個要求，我需要驗證，如果今天的日期是與一個條件匹配，如果真的在數據庫中創建記錄。

但條件是這樣的 - 週二週二，週二週四。 任何人都可以提供如何實現這一點？

Answer 1

private static Calendar cacheCalendar;

  public static LocalDate getNDayOfMonth(int dayweek, int nthweek, int month, int year) { 
          LocalDate d = new LocalDate(year, month, 1).withDayOfWeek(dayweek); 
          if (d.getMonthOfYear() != month) 
              d = d.plusWeeks(1); 
          return d.plusWeeks(nthweek - 1); 
      } 

      public static LocalDate getLastWeekdayOfMonth(int dayweek, int month, int year) { 
          LocalDate d = new LocalDate(year, month, 1).plusMonths(1).withDayOfWeek(dayweek); 
          if (d.getMonthOfYear() != month) 
              d = d.minusWeeks(1); 
          return d; 
      } 

      public static void main(String[] args) { 

          cacheCalendar = Calendar.getInstance(); 

          for (int i = 1; i < 13; i++) { 
              // second wednesday of oct-2011 

              LocalDate secondMonday = getNDayOfMonth(DateTimeConstants.MONDAY, 2, i, cacheCalendar.get(Calendar.YEAR)); 
              System.out.println("secondMonday= " + secondMonday); 

              LocalDate secondTuesday = getNDayOfMonth(DateTimeConstants.TUESDAY, 2, i, 
                      cacheCalendar.get(Calendar.YEAR)); 
              System.out.println("secondTuesday= " + secondTuesday); 

              LocalDate monthlyTuesday = getNDayOfMonth(DateTimeConstants.TUESDAY, 1, i, 
                      cacheCalendar.get(Calendar.YEAR)); 
              System.out.println("monthlyTuesday= " + monthlyTuesday);             

              LocalDate weeklyFirstFriday = getNDayOfMonth(DateTimeConstants.FRIDAY, 1, i, 
                      cacheCalendar.get(Calendar.YEAR)); 
              System.out.println("weeklyFirstFriday= " + weeklyFirstFriday);             


          }         
      }
