What is exception meaning?

An exception in computer programming is an error or unexpected event that occurs during the execution of a program. When an exceptional event occurs, the program cannot continue normal execution and must terminate or take a different path of processing. Exceptions can be caused by a variety of factors, such as invalid input data, hardware or software faults, resource allocation issues, and programming errors. The handling of exceptions is an important aspect of software design and programming, as it can greatly improve the reliability and user experience of a program. Exception handling techniques include catching and re-throwing exceptions, logging errors, notifying users, and recovering from errors in a graceful manner.
