a question about exception

[Simo Hayha]

why does the following code can not compile?
public void amethod()throws IOException{
throw new ProtocolException();
}
can can a method throws Excepton? like this:
public void amethod()throws Exception

Hi There:
I guess error is because amethod declaration says
that it can throw one kind of exception while it
actually throws another kind in the method body...

What is the error message you get when compiling your class? Something like
unreported exception ProtocolException; must be caught or declared to be thrown
throw new ProtocolException();
??
