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 12 - * 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). 13 - * Overloaded constructors can lead to confusion, e.g. if one constructor accepts a float argument and and another one an int argument. Overloaded constructors should be declared as private and functions should be used to create instances whose names highlight the difference. 14 -* No puns or humorous names. 15 -* 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". 16 -* Avoid ambiguities as in the word "add" (addition or adding). 17 -* 3 +**Meaningful and Descriptive Names** 4 + * Choose names carefully, as if naming a child. 5 + * Names should reflect the code's purpose clearly. For example, use unorderedNumbers and orderedNumbers instead of a generic numbers. 6 +1. 18 18 19 -Domain-specific terms 20 - * Use terms from the solution domain. Programmers will be reading your code, so use technical language. 21 - * Use terms from the problem domain. If there are no computer science terms, at least domain experts can refer to them. 22 -* Add meaningful context. Together with the names of other variables and methods, this context can be created. 23 -* Do not add superfluous context. Shorter names are better than longer ones, as long as they are clear. 24 -* Dare to rename things. Your colleagues should be grateful for improvements. 8 +**Avoid Misinformation** 9 + * Steer clear of ambiguous, easily confused names or characters (e.g., l vs. 1, O vs. 0). 10 +1. 11 + 12 +**Clarity in Differences** 13 + * Distinguish names distinctly, avoiding similar expressions and redundant words (e.g., a, an, the, info, data). 14 +1. 15 + 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. 20 + 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 + 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. 30 + 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. 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. 41 + 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.
