# Description
This rule finds and removes unused parameters in private method declarations. Consequently, all the invocations of the affected methods are updated accordingly.
# Benefits
Removes the clutter and simplifies the method declarations.

# Limitations
The non-private methods are not modified by this rule because they could be invoked or overridden in locations that are not reachable by jSparrow.
