Exception

What Does Exception Mean?

An exception is an abnormal or unprecedented event that occurs after the execution of a software program or application. It is a runtime error of an undesired result or event affecting normal program flow.

Techopedia Explains Exception

As a part of every well structured software or hardware appliance, an exception may be classified as one of two broad types: predefined and user defined. Predefined exceptions are native to a system and generally occur when a software developer writes inappropriate code or incorrectly accesses or edits system functionality. A user defined exception is created by a developer to warn end users about certain mistakes or errors.

Exceptions are handled by an exception handler, which helps the underlying system resolve or counteract the exception.
