Query regarding 'EXCEPTION'.Please see.

Question

I have a question regarding Exception.
Lets assume that I have a method that throws an 'ArithmeticException',but
instead of catching this exception,I will catch the 'Exception' object.
try {
    }catch(Exception e){
    } Now correct me if I am mistaken in my analysis :
Normally having a 'superclass and subclass heirarchy' gives you polymorphism.
The subclass will override the method defined in the superclass and gives it
its own implementation.
I can then use the 'superclass reference' as a argument to a method which can execute
the overridden method dynamically.
Because the subclass has overridden the base class method,polymorphism takes place.
Am I right in the above analysis?
Now look at the exception example on top.
I am passing the Exception reference to the catch clause (which is an indirect parent
of ArithmeticException).
My Question is:
1)Which method has ArithmeticException overridden for polymorphism to take place?
(ie,I am passing the superclass of the exception,and the JVM knows which exception to
generate)
2)Am I right in my analysis?

Answer 1

Lets assume that I have a method that throws an
'ArithmeticException',butThen your app is buggy.
instead of catching this exception,I will catch the
'Exception' object.Don't do that. Better fix your code.
Am I right in the above analysis?Yepp, I guess so.
1)Which method has ArithmeticException overridden for
polymorphism to take place?Look at its source. Probably none.
(ie,I am passing the superclass of the exception,and
the JVM knows which exception to
generate)That doesn't make sense. You're not passing anything. The code or JVM knows which exception to generate, and you just tell it which one to catch.
