    Default Mutator method at Beginner level

    Here's the intruction
    The mutator for
    speedInKperHour will check its parameter and use the parameter only if it is not a
    negative number.

    The mutator for driverStanding takes no parameters. It checks the
    speed – if speed is 60 or less, standing will be “no ticket”, if speed is 80 or less,
    standing will be “small ticket” and if speed is more than 80, the standing will be “big
    ticket”.



    Sorry
    I'm not really sure what Mutator to use for these two

    Mutators are used to mutate an instance's attribute, here e.g. setSpeedinkph(int newSpeed)

    Hi,

    Mutator means its a setter method. It just assigns a new values to the variable. As per your requirement, for example you code like this

     
    public void setSpeedInKperHour(int speed)   
    {
                 //Your code goes here
    }

    still you have any doubts post here.

    thanks,
