 An integral approach to code documentation is to write the code so that it documents itself.In other words,the code should be naturally readable in such a way as to make it easy to understand .This is accomplished by proper naming conventions and statement formatting.
一份完整的代码文档是编写可以说明自身的代码。换句话说，代码应该是可读性好，便于理解的，这些是由恰当的命名规则和语句格式实现的。
b)         Collections are the data structures that are most easily altered for performance-tuning purposes. Using the correct or most appropriate collection class can improve performance with little change to code. For example, if a large ordered collection has elements frequently deleted or inserted throughout it, it usually can provide better performance if based on a linked list rather than an array. On the other hand, a static(unchanging) collection that needs to be accessed by index performs better with an underlying implementation that is an array.
集合是为了性能调整目的很容易进行更改的数据结构，使用恰当的集合类可以在对代码进行很小更改的前提下改变程序的性能。例如如果有一个需要经常添加和删除的有序集合，使用链表可以比数组提供更好的性能，在另一方面，一个需要通过索引进行访问的静态集合，使用数组实现将更好一些
