Notice that when
isFactor( )
is called, the arguments are also separated by commas.
When using multiple parameters, each parameter specifies its own type, which can differ
from the others. For example, this is perfectly valid:
Adding a Parameterized Method to Vehicle
You can use a parameterized method to add a new feature to the
Vehicle
class: the ability
to compute the amount of fuel needed for a given distance. This new method is called
fuel-
needed( )
. This method takes the number of miles that you want to drive and returns the
number of gallons of gas required. The
fuelneeded( )
method is defined like this:
Notice that this method returns a value of type
double
. This is useful since the amount of
fuel needed for a given distance might not be a whole number. The entire
Vehicle
class that
includes
fuelneeded( )
is shown here:
