Answer 1

最好的方法
        Calendar cal1 = Calendar.getInstance();
        cal1.set(2005,1,26);
        
        Calendar cal2 = Calendar.getInstance();
        cal2.set(2005,1,30);
        
        int interval = cal2.get(Calendar.DAY_OF_YEAR) - cal1.get(Calendar.DAY_OF_YEAR);
        
        System.out.println(interval);
