Enhance the try statements you wrote as solutions to Exercises 12.28 so that they handle checked and unchecked exceptions in different catch blocks.
Exercises 12.28
The address-book-v3t project includes some throwing of unchecked exceptions if parameter values are null. The project source code also includes the checked exception class No Matching Details Exception, which is currently unused. Modify the remove Details method of Address Book so that it throws this exception if its key parameter is not a key that is in use. Add an exception handler to the remove method of Address Book Text Inter face to catch and report occurrences of this exception.
