-Sometimes extracting the method would result in the new method having a large number of parameters. Alternatively the parameters could be converted to fields of the class. But this would often result in bad [[glossary:​cohesion]]. Because of that in such a case extracting a new class is the next step in adhering to the principle.+Sometimes extracting the method would result in the new method having a large number of parameters.
