Create a program that contains the abstract class $$Shape$$

$$ Create a $$counter$$ member to keep track of the number of objects

instantiated from this superclass

$$ The constructor should increment the counter

$$ Create abstract methods $$area$$ and $$perimeter$$ which will be overridden in

the subclasses

$$ Create method $$getCount$$ to return the number of objects created

$$ Create a finalizer to decrement the object count $($protected void finalize$)$

$17$

Lab $2($cont$)$

Create a $$Circle$$ class that is a subclass of the $$Shape$$ class

$$ Has a private member for the radius

$$ The constructor sets the radius

$$Area$$ method returns PI$*$r$^2$

$$Perimeter$$ method returns $2*$PI$*$r

$$toString$$ method returns $$Circle of radius $[$x$]$

$$ Finalizer should call the super cl
