Exception Handling

Exception handling.

Exception handling is a computer hardware mechanism or programming language construct that handles the occurrence of events.

These events occur during the software execution process and interrupt the instruction flow.

Exception handling performs the specific activities for managing the exceptional events.

The blank can be filled with "Exception handling" as it is the security mechanism that deals with exceptional events in computer hardware or programming language constructs.

Exception handling is a programming language construct that allows programmers to handle exceptional events, such as runtime errors, in a controlled manner. Exceptional events can occur when a program is executing, such as dividing by zero, trying to access an invalid memory address, or encountering an unexpected input. When an exceptional event occurs, the program transfers control to the exception handling mechanism, which then determines how to handle the event.

The primary goal of exception handling is to provide a mechanism for handling exceptional events that occur during program execution without crashing the program. By handling exceptions gracefully, programmers can write more robust and reliable software.

Exception handling involves several key components, including the exception class, exception handler, and throw statement. The exception class defines the type of exception that occurred, the exception handler is responsible for handling the exception, and the throw statement is used to trigger the exception.

In summary, exception handling is an essential security mechanism that helps software developers write robust and reliable code by handling exceptional events that occur during program execution.
