About a clause in MC selection

[anson chau]

what exactly is meant by 'An Exception is thrown at runtime?"

(A) A RuntimeException(ONLY exception that extends RuntimeException) will be thrown ?

(B) An Exception is thrown at program running time, no matter it is unchecked or checked.

Thank you.

I take that to mean 'B'.

Isn't it also true that any exception thrown at runtime will also extend RuntimeException (whether progammer or JVM initiated)? I would think both A and B are implied...

No. Runtime is the only time your code can throw anything.

RuntimeException is simply a subclass of Exception, and serves as a distinction between checked and unchecked exceptions.
