overriding methods: doubt

[rijagu chan]

One of the answers is the overiding method must not throw any exceptions that may not be thrown by the overridden method.
My question is what about a RuntimeException. What if I throw an ArithmeticException explicitly only in the overiding method.
void overriddenMethod() { }
void overridingMethod() throws ArithmeticException { }

The statement is a bit ambiguous. If it means only checked exceptions then it's correct but if it means any kind of exception, it's wrong.

A RuntimeException can be thrown by the overridden method or the overriding method. The statement only talks about exceptions that can not be thrown by the overridden class, and so it has nothing to with RuntimeExceptions (or Errors for that matter). The statement is definitely true.
