Implement $3$ classes based on the following requirements:

Person class$($needs to inherit from Object class$)$:

Instance variables $($all private$)$:

$-$name

$-$address

Constructor:

$-$initializes name and address

Instance methods:

$-$getter and setters for name and address

$-$toString$()$ method that returns name and address values

Student class $($needs to inherit from Person class$)$:

Instance variables $($all private$)$:

$-$program

$-$year

$-$fee

Constructor:

$-$initializes all fields $($name$,$ address,program, year, fee$).$ Use super$()$ to initialize superclass variables.

Instance methods:

$-$getter and setters for program, year, fee.

$-$toString$()$ method that returns the values of all fields$($name$,$ address,program, year, fee$).$ Use super to call super class toString$()$ method.

Staff class $($needs to inherit from Person class$)$:

Instance variables $($all private$)$:

$-$school

$-$pay

Constructor:

$-$initializes all fields $($name$,$ address,school, pay$).$ Use super$()$ to initialize superclass variables.

Instance methods:

$-$getter and setters for school, pay.

$-$toString$()$ method that returns the values of all fields$($name$,$ address,school, pay$).$ Use super to call super class toString$()$ method.

Once the implementation is done, create object of Student and Staff classes call their respective toStrings methods to check for correct implementation.

In particular, call toString$()$ method to check if it is being overridden correctly from Object class.
