What is Exception in Programming?

In programming, an exception is an event that occurs during the execution of a program, which interrupts the normal flow of the program’s instructions.

An exception is typically caused by an error or some other unexpected condition that prevents the program from continuing to execute as intended. Examples of exceptions include:

  • Attempting to access a file that does not exist
  • Dividing a number by zero
  • Calling a method on a null object
  • Running out of memory

When an exception occurs, the program will typically halt its normal execution and jump to a special section of code called an exception handler. The exception handler will then attempt to handle the exception in an appropriate way, which could include displaying an error message, logging the exception, or taking some other action to address the issue that caused the exception.

By using exceptions, programmers can write more robust and fault-tolerant code, as they can anticipate and handle unexpected conditions that could cause the program to crash or produce incorrect results.
