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.
1 +1.
2 2  
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 -*
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.

14 -**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.
15 -* **No puns or humorous names.**
16 -* **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".
17 -* **Avoid ambiguities** as in the word "add" (addition or adding).
18 -* **Domain-specific terms**
19 - * Use terms from the solution domain. Programmers will be reading your code, so use technical language.
20 - * Use terms from the problem domain. If there are no computer science terms, at least domain experts can refer to them.
21 -* **Add meaningful context.** Together with the names of other variables and methods, this context can be created.
22 -* **Do not add superfluous context.** Shorter names are better than longer ones, as long as they are clear.
23 -* **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.
