A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the function is doing too many things.

Noncompliant Code Example

With a maximum number of 4 parameters:

public void doSomething(int param1, int param2, int param3, String param4, long param5) {
...
}

Compliant Solution

public void doSomething(int param1, int param2, int param3, String param4) {
...
}

Exceptions

Methods annotated with :

• Spring's @RequestMapping (and related shortcut annotations, like @GetRequest)
• JAX-RS API annotations (like @javax.ws.rs.GET)
• Bean constructor injection with @org.springframework.beans.factory.annotation.Autowired
• CDI constructor injection with @javax.inject.Inject
• @com.fasterxml.jackson.annotation.JsonCreator

may have a lot of parameters, encapsulation being possible. Such methods are therefore ignored.

Cognitive Complexity is a measure of how hard the control flow of a method is to understand. Methods with high Cognitive Complexity will be difficult to maintain.
