For example, use `unorderedNumbers` and `orderedNumbers` instead of a generic `numbers`. 4 -* **Avoid Misinformation** 5 - * Steer clear of ambiguous, easily confused names or characters (e.g., l vs. 1, O vs. 0). 6 -* **Clarity in Differences** 7 - * Distinguish names distinctly, avoiding similar expressions and redundant words (e.g., a, an, the, info, data). 8 -* **Pronounceable and Searchable Names** 9 - * Use names that are easy to pronounce and discuss. 10 - * Name length should match its scope: short for local loops, longer for broader usage. 11 -* **No Encodings or Mental Mappings** 12 - * Avoid including type or scope information in names. 13 - * Names should be clear without requiring mental translation, meaning any effort of the programmer to get the actual purpose 14 -* **Naming Conventions for Classes and Methods** 15 - * Class names: Use nouns or noun phrases. 16 - * Method names: Use verbs or verb phrases, adhering to standards like JavaBean (get, set, is, has). Utilize descriptive function names instead of overloaded constructors. 17 -* **Avoid Inappropriate Humor and Ambiguities** 18 - * Refrain from humorous names. 19 - * Choose one word per concept to maintain consistency (e.g., always use "get" instead of alternating with "fetch" or "retrieve"). 20 - * Avoid puns and ambiguous terms (like "add" for addition or appending). 21 -* **Domain-Specific Naming** 22 - * Use technical terms (solution domain) for clarity among programmers. 23 - * Use terms from the problem domain when no technical equivalents exist, aiding domain experts. 24 -* **Context and Simplicity in Naming** 25 - * Provide meaningful context through combined variable and method names. 26 - * Avoid unnecessary context; opt for shorter, meaningful names. 27 - * Be open to renaming for clarity and improvement. 1 +* 2 + 3 +Choose meaningful names. 4 + * Names should be chosen as carefully as the name of his firstborn child. 5 + * Implicity: It should be self-evident from reading the code how it works. 6 +* 7 + 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 +* 11 + 12 +Avoid misinformation. 13 + * For example, ambiguities, confusion with similar names or easily confused characters (l and 1, O and 0). 14 +* 15 + 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 +* 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 +* 25 + 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 +
