For example, use unorderedNumbers and orderedNumbers instead of a generic numbers. 6 +1. 7 7 8 - Choosenames thatare descriptiveof the purpose.9 - * Forexample,avariablesname shouldstandfor one concept.

Programming is a social activity that people talk about with others. 20 -* 16 +**Pronounceable and Searchable Names** 17 + * Use names that are easy to pronounce and discuss. 18 + * Name length should match its scope: short for local loops, longer for broader usage. 19 +1. 21 21 22 -Use searchable names. 23 - * The length of a name should correspond to the size of its scope. For local counting loops, one letter is enough; if the variable is used in multiple places in the code, it needs a longer name. 24 -* 21 +**No Encodings or Mental Mappings** 22 + * Avoid including type or scope information in names. 23 + * Names should be clear without requiring mental translation. 24 +1. 25 25 26 -Avoid encodings. 27 - * There should be no references to the scope or type of the variable in the name. 28 -* 26 +**Naming Conventions for Classes and Methods** 27 + * Class names: Use nouns or noun phrases. 28 + * Method names: Use verbs or verb phrases, adhering to standards like JavaBean (get, set, is, has). Utilize descriptive function names instead of overloaded constructors. 29 +1. 29 29 30 -Avoid mental mappings. 31 - * The name of a variable should not have to be mentally translated into another. Clarity has absolute priority. 32 -* 31 +**Avoid Inappropriate Humor and Ambiguities** 32 + * Refrain from humorous names. 33 + * Choose one word per concept to maintain consistency (e.g., always use "get" instead of alternating with "fetch" or "retrieve"). 34 + * Avoid puns and ambiguous terms (like "add" for addition or appending). 35 +1. 33 33 34 -Class names 35 - * Names of classes consist of nouns or substantivistic expressions. 36 -* 37 +**Domain-Specific Naming** 38 + * Use technical terms (solution domain) for clarity among programmers. 39 + * Use terms from the problem domain when no technical equivalents exist, aiding domain experts. 40 +1. 37 37 38 -Method names 39 - * They consist of a verb or an expression with a verb. Accessors, mutators, and predicates should be named after their value and follow the JavaBean standard (prefixes: get, set, is, has). 40 - * Overloaded constructors can lead to confusion, e.g. if a float is to be passed once and an int once. Constructors should be declared as private and functions should be used to create instances whose names highlight the difference. 41 -* Avoid humorous names. 42 -* 43 - 44 -Choose one word per concept. 45 - * "get" instead of "fetch" and "retrieve". 46 -* No puns. 47 -* Avoid ambiguities as in the word "add" (addition or adding). 48 -* 49 - 50 -Use names of the solution domain. 51 - * Programmers will read your code, so use technical language. 52 -* 53 - 54 -Use names of the problem domain. 55 - * If there are no terms from computer science. Then at least domain experts can refer to it. 56 -* 57 - 58 -Add meaningful context. 59 - * Together with the names of other variables and methods, this context can be created. 60 -* 61 - 62 -Do not add superfluous context. 63 - * Shorter names are better than longer ones, as long as they are clear. Names should be simple, but meaningful. 64 -* Dare to rename things. Your colleagues should be grateful for improvements. 65 - 66 - 42 +**Context and Simplicity in Naming** 43 + * Provide meaningful context through combined variable and method names. 44 + * Avoid unnecessary context; opt for shorter, meaningful names. 45 + * Be open to renaming for clarity and improvement.
