Exception is not an error,It's abnmormal
condition.Exceptions will be raise at runtime.if you want
to handle exception,we can use try-catch block.
There are 2 types of exception.
1).System Exception
2).Application Exception
The above two exception are genarated from "Exception" base
class.
SystemException: is meant only for those exceptions defined
by the common language runtime.
Ex:NullReferenceException
ApplicationException: is thrown by a user program.
By using this,we can throws our own exception message.
