Yes, you are right, it is redundant. It is just an exercise to show
you that you may always create another constructor with additional
parameters.
If you find it more useful, you may create say birthDate, or
birthPlace, or what you like. And have that new constructor allows you
to construct a new StudentRecord instance with this parameter.
Or you may compare the calculation of the average of grades based upon
individual grades to the one you pass, and change (with appropriate
getters and setters) the average parameter you enter.
There is no limit here to your imagination.
