E.g. counters only used locally in loops, could be short or even single letters, but names used in a broad scope should be more descriptive and longer. 18 - * Avoid encodings, such as references to the variable's scope or type in its name. 8 +Choose names that are descriptive of the purpose. 9 + * 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. 10 +* 19 19 20 -**Class and Method Naming** 12 +Avoid misinformation. 13 + * For example, ambiguities, confusion with similar names or easily confused characters (l and 1, O and 0). 14 +* 21 21 22 -* **Class Names** 23 - * Should consist of nouns or noun phrases. 24 -* **Method Names** 25 - * Should consist of verbs or verb phrases. 26 - * Follow the JavaBean standard for accessors, mutators, and predicates (prefixes: get, set, is, has). 27 - * Use distinct names for overloaded constructors and prefer private constructors with distinct factory methods. 16 +Make differences clear. 17 + * Avoid very similar expressions. 18 + * Blank words are redundant (a, an, the, info, data). 19 +* Use pronounceable names. Programming is a social activity that people talk about with others. 20 +* 28 28 29 -**General Coding Practices** 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 +* 30 30 31 -* **Avoiding Confusion and Misinformation** 32 - * Avoid humorous names, puns, and any names that might cause confusion. 33 -* **Contextual Naming** 34 - * Add meaningful context that complements other variable and method names. 35 - * Dare to rename things for clarity and improvement; colleagues should appreciate these enhancements. 26 +Avoid encodings. 27 + * There should be no references to the scope or type of the variable in the name. 28 +* 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 +* 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 +
