獲取日期時間dayOfWeek/dayOfMonth as String

Question

如何將星期幾或月份作爲字符串獲取？而不必像做：

 DateTime now = DateTime.now(); 
     String dayOfWeek = null; 
     switch(now.getDayOfWeek()) { 
      case DateTimeConstants.MONDAY: 
       dayOfWeek = "Monday"; 
       break; 
      case DateTimeConstants.TUESDAY: 
       dayOfWeek = "Tuesday"; 
       break; 
      case DateTimeConstants.WEDNESDAY: 
       dayOfWeek = "Wednesday"; 
       break; 
      case DateTimeConstants.THURSDAY: 
       dayOfWeek = "Thursday"; 
       break; 
      case DateTimeConstants.FRIDAY: 
       dayOfWeek = "Friday"; 
       break; 
      case DateTimeConstants.SATURDAY: 
       dayOfWeek = "Saturday"; 
       break; 
      case DateTimeConstants.SUNDAY: 
       dayOfWeek = "Sunday"; 
       break; 
     } 

Answer 1

嗯，顯然這只是dateTime.dayOfWeek().getAsText();如記錄here。

Answer 2

您可以使用上述邏輯創建DateTime擴展方法，並根據需要使用，而不必重複整個邏輯。
