Name Specify the name for the new parameter.
Declare finalSelect this option to declare the parameter final.
Delegate via overloading methodSelect this option to keep the existing method calls unchanged.

The call to the new method will be added to the old method. The necessary value (or expression) will be passed to the new method in this call.
