Write an ElectricVehicle $($note the Pascal$-$case naming here$)$ class that represents an electric vehicle. ElectricVehicle instances know their names $($String$),$ battery size $($double$),$ state of charge $($double$),$ current efficiency $($double$),$ and default efficiency $($double $-$ the "rated" efficiency of the vehicle$).$

An electric vehicle calculates its range by multiplying its current efficiency $*$ state of charge $*$ battery size.
