1 -Names should be chosen as carefully as the name of your first-born child. It should be obvious from reading the code how it works.
2 -
3 -* **Names describe purpose.** For example, it's 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 independent things with the same name. 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). For example, getAge(), setAge(...), isFeatureXEnabled() -> boolean, hasPermission() -> boolean etc.
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.
1 +* **Meaningful and Descriptive Names**
2 + * Choose names carefully, as if naming a child.
3 + * Names should reflect the code's purpose clearly. 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.
