Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

The underlying implementation of String::replaceAll
calls the java.util.regex.Pattern.compile()
method each time it is
called even if the first argument is not a regular expression. This has a significant performance cost and therefore should be used with care.
When String::replaceAll
is used, the first argument should be a real regular expression. If it’s not the case,
String::replace
does exactly the same thing as String::replaceAll
without the performance drawback of the regex.
This rule raises an issue for each String::replaceAll
used with a String
as first parameter which doesn’t contains
special regex character or pattern.
Noncompliant Code Example
String init = "Bob is a Bird... Bob is a Plane... Bob is Superman!"; String changed = init.replaceAll("Bob is", "It's"); // Noncompliant changed = changed.replaceAll("\\.\\.\\.", ";"); // Noncompliant
Compliant Solution
String init = "Bob is a Bird... Bob is a Plane... Bob is Superman!"; String changed = init.replace("Bob is", "It's"); changed = changed.replace("...", ";");
Or, with a regex:
String init = "Bob is a Bird... Bob is a Plane... Bob is Superman!"; String changed = init.replaceAll("\\w*\\sis", "It's"); changed = changed.replaceAll("\\.{3}", ";");

Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 84.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.
See codeclimate-duplication
's documentation for more information about tuning the mass threshold in your .codeclimate.yml
