1·Now that it's time to begin iterating on the design, the book describes two different options — Use case or Feature-driven development — and discusses when one approach is better than the other.
因为是时候开始对设计进行迭代了，所以该书介绍了两种不同的选项——用例或特性驱动的开发——并讨论什么时候一个会比另一个更好。
2·The Collections framework introduced iterators for traversing a list or other collection, which optimizes the process of iterating through the elements in a collection.
集合框架引入了迭代器，用于遍历一个列表或者其他集合，从而优化了对一个集合中的元素进行迭代的过程。
3·As soon as you start keeping track of array offsets, your code will get much more complicated so any time you can avoid iterating through an array by index you should.
一旦您开始跟踪数组偏移，您的代码就会变得更加复杂，以至于任何时候您都应该避免通过索引迭代通过一个数组。
4·Simply iterating over the numbers from one to ten, say, with XSLT 1.0 is clumsy if the number of times your template needs to iterate bears no relationship to the input document.
比方说，简单地从一迭代到十，如果模板需要迭代的次数和输入文档没有什么关系，使用 XSLT 1.0 完成这个任务就非常麻烦。
5·An application iterating over such a modified stream would not need to know that it was manipulated.
迭代修改过的流的应用程序不需要知道它处理的是什么。
