Exception
Updated: 08/02/2019 by Computer Hope
In computer programming, an exception is a special condition encountered during program execution that is unexpected or anomalous. For example, if a program tries to open a file that doesn't exist or gets a read error, this condition is an exception.
Exceptions must be anticipated by the programmer and properly handled in the program code, branching program execution as appropriate to avoid a fatal error. This aspect of computer programming is known as exception handling.
