Introduction to exception handling

Exception handling enables a programmer to cater for exceptional or problematic scenarios by defining a method of overriding the normal program flow during execution. When an exception occurs the normal program flow is interrupted and execution is directed to a piece of code in place to handle the exception which is called the catch statement.
