1 +Names should be chosen as carefully as one would name their firstborn child.
2 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 -*
3 +**Naming Conventions**
7 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 -*
5 +* **Choose Meaningful and Descriptive Names**
6 + * Names should be descriptive of the purpose, e.g., use `unorderedNumbers` and `orderedNumbers` instead of a generic `numbers`.
7 + * Use names that reflect the solution domain and the problem domain.
8 + * Choose one word per concept (e.g. consistently use 'fetch' for the same concept, rather than mixing 'fetch' and 'retrieve').
9 +* **Clarity and Simplicity in Names**
10 + * Names should be self-evident and avoid mental mappings or translations for clarity.
11 + * Avoid ambiguities, such as confusion with similar names or characters (e.g., l and 1, O and 0).
12 + * Make differences clear and avoid very similar expressions.
13 + * Avoid superfluous or redundant context; shorter names are better as long as they are clear.
14 +* **Practical Aspects of Naming**
15 + * Use pronounceable names so that you can easily talk with others about it.
16 + * Use searchable names, meaning names which prevent search conflicts.
17 + * The length of a name should correspond to the size of its scope. 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.

12 -Avoid misinformation.
13 - * For example, ambiguities, confusion with similar names or easily confused characters (l and 1, O and 0).
14 -*
20 +**Class and Method Naming**
15 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 -*
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.
21 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 -*
29 +**General Coding Practices**
25 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 -*

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.

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.
