对多个元素的聚合进行遍历访问时，需要依次推移元素，例如对数组通过递增下标的方式，数组下标功能抽象化、一般化的结果就称为迭代器(Iterator)。模式以下程序模拟将书籍(Book)放到书架(BookShelf)上并依次输出书名。这样就要涉及到遍历整个书架的过程。使用迭代器Iterator实现。图6-1显示了各个类间的关系。以下是JAVA语言实现，能够正确编译通过。

A centuries-old tradition，illustrated in a modem children's book. 1inks the sweetness of honey with the joy of learning to read.

“The grandpa held a jar of honey so that all the family could see. He then dipped a spoon into it and put some honey on the cover of a small book.

The little girl had just turned five.

‘Stand up，little one，’he asked the girl softly. ‘I did this for your mother，your uncles，your older brother，and now you!’

Then，he handed the book to her. ‘Taste!’

She touched the honey with her finger and put it into her mouth.

‘What's that taste?’the grandpa asked.

The little girl answered，‘Sweet!’

Then all of the family said in a single voice，‘Yes，and so is knowledge，but knowledge is from the bee that made that sweet honey，you have to go after it through the pages of a book!’

The little girl knew that the promise to read was at last hers. Soon she was going to learn to read. ”

This is the beginning of a profoundly moving children's book entitled Thank You，Mr. Falker. In this book，Patricia Polacco writes of her own passion to read，inspired by the honey on the book. It wasn't until fifth grade that she met her beloved teacher who provided the hlep that she needed to finally unlock the magic of the written word.

Reading this book，we are in fact acquainted with some enduring traditions of child education that stress the importance of verbal capacity at a very early age.

The child learning to read is admitted into a collective memory by way of books. And with the printed words that are active with meaning，the child becomes acquainted with a common past which he or she renews，to a greater or lesser degree，in every reading. Much as the author of the book Thank You，Mr. Falker puts it，“Almost as if it were magic，or as if light poured into her brain，the words and sentences started to take shape on the page as they never had before…And she understood the whole thing…Then she went into the living room and found the book on a shelf，the very book that her grandpa had shown her so many years ago. She spooned honey on the cover and tasted the sweetness…Then she held the book，honey and all，close to her chest. She could feel tears roll down her cheeks，but they weren't tears of sadness-she was happy，so very happy. ”

The girl who tasted the honey on the book was______.

A．nearly six years old

B．less than five years old

C．more than six years old

D．a little more than five years old
