Query regarding Exception and invocation.

Question

I have a query regarding Exception.
In my code, which throws an ArithmeticException:
<code>
public class TestArithmeticException{
public static void main(String[] args)
int a,b ;
try {
b=0;
a = 50/b;
}catch(Exception ex) {
ex.printStackTrace()
</code>
The above code is catching exception of type Exception(which is superclass of all RuntimeExceptions)
and which inturn extends the Throwable class.
ie. Throwable -
Exception -
RuntimeException
ArithmeticException
Am I correct in my assumption below:
a Because ArithmeticException is an indirect subclass of Throwable and has access to its inherited methods,
it overrides the methods defined in 'Throwable', and then via polymorphism(superclass reference 'ex' in the catch clause)
invokes the method ex.printStackTrace() ?
Does it mean that all runtime exception child classes override the methods defined in Throwable, and then via polymorphism execute overridden
methods?

Answer 1

Yes.
