 Grammatical naming conventions are more flexible and more controversial than typographical conventions. There are no grammatical naming conventions to speak of for packages. Instantiable classes, including enum types, are generally named with a singular noun or noun phrase, such as Thread, PriorityQueue, or ChessPiece. Non-instantiable utility classes (Item 4) are often named with a plural noun, such as Collectors or Collections. Interfaces are named like classes, for example, Collection or Comparator, or with an adjective ending in able or ible, for example, Runnable, Iterable, or Accessible. Because annotation types have so many uses, no part of speech predominates. Nouns, verbs, prepositions, and adjectives are all common, for example, BindingAnnotation, Inject, ImplementedBy, or Singleton.
 
-语法命名约定比排版约定更灵活，也更有争议。包没有语法命名约定。可实例化的类，包括枚举类型，通常使用一个或多个名词短语来命名，例如 Thread、PriorityQueue 或 ChessPiece。不可实例化的实用程序类（[Item-4](/Chapter-2/Chapter-2-Item-4-Enforce-noninstantiability-with-a-private-constructor.md)）通常使用复数名词来命名，例如 collector 或 Collections。接口的名称类似于类，例如集合或比较器，或者以 able 或 ible 结尾的形容词，例如 Runnable、Iterable 或 Accessible。因为注解类型有很多的用途，所以没有哪部分占主导地位。名词、动词、介词和形容词都很常见，例如，BindingAnnotation、Inject、ImplementedBy 或 Singleton。

 Methods that perform some action are generally named with a verb or verb phrase (including object), for example, append or drawImage. Methods that return a boolean value usually have names that begin with the word is or, less commonly, has, followed by a noun, noun phrase, or any word or phrase that functions as an adjective, for example, isDigit, isProbablePrime, isEmpty, isEnabled, or hasSiblings.
