Output: A refrence to super can refer to sub class over ridden

Methods

Therefore create a referecne to super

A refrence to super

Inside Shape. No definite Area

A refrence to Circle

Inside Circle. Area=PI*r*r

A refrence to Triangle

Inside Triangle. Area=0.5*base*alt

Line Nos. 17–19: create objects to classes Shape, Circle and Triangle. Shape is super class

and Circle and triangle are subclasses, as shown in Line Nos. 6 and 10.

Each subclass Circle and Triangle has overridden super method Find-

Area()

in Line Nos. 8 and 11.

Line No. 22: obtains a reference to super class object. Line Nos. 24, 27 and 30 show ...
