Clarity has absolute priority. 32 -* 33 - 34 -Class names 35 - * Names of classes consist of nouns or substantivistic expressions. 36 -* 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 - 3 +* **Choose names that are descriptive of the purpose.** For example, a variables name should stand for one concept. Its better to have a variable `unorderedNumbers`, which is sorted and stored in `orderedNumbers` instead of saving both lists in the same variable `numbers`. 4 +* **Avoid misinformation.** For example, ambiguities, confusion with similar names or easily confused characters (l and 1, O and 0). 5 +* Make differences clear. Avoid very similar expressions and blank words are redundant (a, an, the, info, data). 6 +* **Use pronounceable names.** Programming is a social activity that people talk about with others. 7 +* **Use searchable names.** Searchable means avoiding search conflicts with other similar or even identical names. The length of a name should match the size of its scope. For local counting loops, one letter is sufficient; if the variable is used in several places in the code, it needs a longer name. 8 +* **Avoid encodings.** There should be no references to the scope or type of the variable in the name. 9 +* **Avoid mental mappings.** The name of a variable should not require mental effort to understand. For example, unusual abbreviations should be avoided. 10 +* **Names of classes consist of nouns** or substantivistic expressions. 11 +* **Method names** **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). 12 +* **Use object creation functions rather than overloaded constructors**, as the latter can cause confusion. Overloaded constructors should be declared private, and functions should be used to create instances whose names make the difference clear. 13 +* **No puns or humorous names.** 14 +* **Choose one word for each concept.** For example, if you use the word "fetch" once for a particular concept, you should consistently use "fetch" instead of synonyms such as "retrieve". 15 +* **Avoid ambiguities** as in the word "add" (addition or adding). 16 +* **Domain-specific terms** 17 + * Use terms from the solution domain. Programmers will be reading your code, so use technical language. 18 + * Use terms from the problem domain. If there are no computer science terms, at least domain experts can refer to them. 19 +* **Add meaningful context.** Together with the names of other variables and methods, this context can be created. 20 +* **Do not add superfluous context.** Shorter names are better than longer ones, as long as they are clear. 21 +* **Dare to rename things.** Your colleagues should be grateful for improvements.
