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

The following code snippet illustrates this rule with a maximum number of 4 parameters:

    function doSomething(param1, param2, param3, param4, param5) {
    ...
    }

## Compliant Solution

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