1		-Names should be chosen as carefully as the name of his firstborn child. Implicity: It should be self-evident from reading the code how it works.
	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	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`.
	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	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).
	5	+* **Make differences clear.** Avoid very similar expressions and blank words are redundant (a, an, the, info, data).
6	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.
	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	8	* **Avoid encodings.** There should be no references to the scope or type of the variable in the name.
9	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		-* Avoid humorous names.
15		-* Choose one word per concept.
16		- * "get" instead of "fetch" and "retrieve".
17		-* No puns.
18		-* Avoid ambiguities as in the word "add" (addition or adding).
19		-* Use names of the solution domain.
20		- * Programmers will read your code, so use technical language.
21		-* Use names of the problem domain.
22		- * If there are no terms from computer science. Then at least domain experts can refer to it.
23		-* Add meaningful context.
24		- * Together with the names of other variables and methods, this context can be created.
25		-* Do not add superfluous context.
26		- * Shorter names are better than longer ones, as long as they are clear. Names should be simple, but meaningful.
27		-* Dare to rename things. Your colleagues should be grateful for improvements.
	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.
