Session 6

* Today we talked about the Try-Catch set of statements as well as the various types of exceptions used when handling errors.
* An exception is a class of objects.
* All exceptions share certain characteristics.
* Some of the possible exception types include:
1. ArgumentNullException - a variable that has no value is passed to a procedure;
2. DivideByZeroException - a value is divided by zero;
3. FormatException - a variable is converted to another type that is not possible;
4. NullReferenceException - a procedure is called when the result is not possible;
5. OverflowException - a value exceeds its assigned data type;
6. SystemException - used to catch all generic exceptions.
