如何使用Java EWS api删除整个Exchange日历程序活动？

ExchangeService service = new ExchangeService();
service.setUrl(new URI("Exchange服务器URL"));
service.setCredentials(new WebCredentials("用户名", "密码"));

CalendarFolder calendarFolder = CalendarFolder.bind(service, WellKnownFolderName.Calendar);
ItemView view = new ItemView(100); // 设置要获取的日历程序活动数量
FindItemsResults<Item> findResults = calendarFolder.findItems(view);

for (Item item : findResults.getItems()) {
    item.delete(DeleteMode.HardDelete);
}

System.out.println("日历程序活动删除成功！");
