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”


I'm not sure what Mutator Method to use for these two.

I'll give 50 FG to whoever help me with this.

1 - You need to post all your relevant code that you have so far

2 - Don't pm people, just post it here

in the future, use code tags w/ proper indenting ;o

Didn't specify which language to use..

To actually answer your question:

You will commonly see the words "mutator" and "accessor" tossed around when referring to methods. Typical naming conventions for these contain the prefixes "set" for the mutator and "get" for the accessor.




So, let's say you have some class Speedometer which has a private field speedInKperHour



You will presumably want to mutate(set) or access(get) the current speed. But you don't want to expose all of your fields to the user, so we make it private and expose only the methods



Above contains a stub for the mutator. Given the problem specs, what logic would you need to implement so that the mutator functions as needed?
