I think option B is also correct !! Multi argument constructors can throw Exceptions using the 'throws' clause. In the JLS all they say is that: the throws clause of the construcor is identical in structure and behavior to the throws clause of a method. So I guess both B can throw Exceptions. Hope this helps !! Regds, Milind

Miland, Please read the qstn once more. It says, An exception can only be thrown by a multi argument constructor. > This only word makes the answer false. Because other overloaded constructors also CAN throw Exception at their will. So ans a) c) d) are correct regds [This message has been edited by maha anna (edited April 01, 2000).]

My preceding message didn't show.. ? I'll give it a try again: I think the answers are only a) and d). Only METHODS can declare they throw Exceptions. Not CLASSES. JRoch

Well, I am a newbie and haven't registered yet, but I have to say that D isn't quite correct either. The finally clause may not be exectued if the JVM exits, but also if the Thread executing the code containing the finally dies, not throws an exception but dies. Is this true?? rch-tech
