checked exceptions
<p>I have been revising for a java exam. I'm not sure how to answer the following question about checked exceptions. Any help is appreciated. Cheers</p>

<p>InvalidMemberIdException is a checked exception class. It has two
constructors: one that takes no parameters and the other that takes a single String
parameter that is used as the message associated with the exception when it is
thrown.
Write the full definition of the InvalidMemberIdException class.</p>
