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.

Merging collapsible if
statements increases the code's readability.
Noncompliant Code Example
if (file != null) { if (file.isFile() || file.isDirectory()) { /* ... */ } }
Compliant Solution

Sometimes two consecutive 'if' statements can be consolidated by separating their conditions with a boolean short-circuit operator.
Example:
void bar() {
if (x) { // original implementation
if (y) {
// do stuff
}
}
}
void bar() {
if (x && y) { // optimized implementation
// do stuff
}
}
