Answer 1

以下代码打印

     DateTimeFormat format2 = DateTimeFormat.getFormat("E");
     String format = format2.format(new Date());
     System.out.println(format); //prints "Mon"

所以

if (rt.detalization.equals("week")) {  
       DateTimeFormat format2 = DateTimeFormat.getFormat("E");
    String day= format2.format(dtfDate);              
         System.out.println(day+"-Sun");

}
