ready to do validation of the data items that are given as instance values for our objects. A variety of validation tests will be required, depending on the data type of the instance variable involved. Unacceptable data values will trigger exceptions in the code; exceptions will be instantiated to include a clear description of the issue and available information to help in locating or debugging the problem. Those exceptions must then be 'thrown' and passed up the call stack to the controlling process for proper handling.
