Each class variable needs its own set function instea XN$14$ d of one common one.

And the set functions must check whether the user has entered valid values.

PLEASE HELP I RECEIRVED A FAILED FOMEWORK MARK :(

Define a class Date that contains integer variables for the day, month, and year.

$1\mathrm{.}1.$ Create the necessary methods for the class: set, get, default constructor, constructor with arguments.

$1\mathrm{.}2.$ Create a method that calculates the number of days between two dates $($objects$)$ submitted to it$.$

$1\mathrm{.}3.$ Create a dateUpdate method that calculates the next day $($assuming $30$ days in each month$)$

Define a class Class that contains integer variables hours and minutes. Class Time inheritance class Date members.

$2\mathrm{.}1.$ Create the necessary methods for the class: set, get, default constructor, constructor with arguments.

$2\mathrm{.}2.$ Create a timeUpdate method that calculates time after one minute.

$2\mathrm{.}3.$ Create a method dateAndTime, which calculates the time after one minute taking into account the date $($if it is $23$:$59,$ then after one minute the time will be $00$:$00$ the next day; if the same time is on December $31,$ then after one minute the new year will be $).$

Write a program implementation that demonstrates all the methods in both classes."
