Download the Activtity Exceptions project from activity.zipDownload activity.zip

The Activity class does not do any exception checking. Modify it so that you handle any exceptions that could occur. Note that you should not change Fraction.java.

Think carefully about your design and use good object$-$oriented principles in your implementation.
