hello all,
please confirm the answer with reason:
Question 28: Imagine there are two exception classes called Exception1 and Exception2 that descend from the Exception class. Given these two class definitions: class First {
void test() throws Exception1, Exception2 { . . . }
}
class Second extends First {
void test() { . . . }
}
Create a class called Third that extends Second and defines a test() method. What exceptions can Third�s test() method throw?
Select all valid answers.

1 -Exception1
2 -Exception2
3 -no checked exceptions
4-any exceptions declared in the throws clause of the Third�s test() method.
ans 3
i think it should be 1 & 2.

The choice 3 is more appropriate than 1 &2.
As the overriding method test() in class Second is not throwing any CheckedExceptions, The Third class's test() method should not throw any checked exceptions. But it is free to throw any runtime exceptions.
Also remember the overriding method can only throw same checked Exception or subclass of that checked exception or nothing.

Hi Kriti,
I'm going to move this post to Certification Study as it's not related to Certification Results.
