Question

我正在尝试将日期转换为String，但它给了我一个 java.lang.IndexOutOfBoundsException ，我真的不知道为什么。我的代码： `

DateFormat df = new SimpleDateFormat("HH:mm");
String tempStartTime =df.format(currentAgenda.getFestivals().get(0).getFestivalBeginTime());
String tempEndTime = df.format(currentAgenda.getFestivals().get(0).getFestivalEndTime());`

当我尝试运行程序时，它给了我这些错误：

方法getFestivalBeginTime和getFestivalEndTime都返回一个Date对象，所以我不明白为什么这应该是错的？提前谢谢！
