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"

Define a constant instead of duplicating this literal "Trying to load file from '" 4 times. Open
logger.warning("Trying to load file from '" + file.getAbsolutePath() + "' path, but it's not readable.\n");- Read upRead up
- Exclude checks
Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
Noncompliant Code Example
With the default threshold of 3:
public void run() {
prepare("action1"); // Noncompliant - "action1" is duplicated 3 times
execute("action1");
release("action1");
}
@SuppressWarning("all") // Compliant - annotations are excluded
private void method1() { /* ... */ }
@SuppressWarning("all")
private void method2() { /* ... */ }
public String method3(String a) {
System.out.println("'" + a + "'"); // Compliant - literal "'" has less than 5 characters and is excluded
return ""; // Compliant - literal "" has less than 5 characters and is excluded
}
Compliant Solution
private static final String ACTION_1 = "action1"; // Compliant
public void run() {
prepare(ACTION_1); // Compliant
execute(ACTION_1);
release(ACTION_1);
}

To prevent generating some false-positives, literals having less than 5 characters are excluded.
