Exception handling is based on the concept of exceptions, which are events that occur during the execution of a program that disrupt the normal flow of control. When an exception is thrown, the program jumps to a specific block of code called an exception handler, which can take appropriate action to handle the exception.
Traditional error handling, on the other hand, is based on the concept of returning error codes or status flags. In this approach, functions and methods return a value indicating whether they were successful or not, and the caller is responsible for checking the return value and taking appropriate action.
Exception handling is more structured and easier to understand than traditional error handling. It separates the error handling code from the normal code, making it more clear which code is responsible for handling errors.
Exception handling allows you to handle multiple types of errors with a single catch block, where traditional error handling can require multiple if-else statements or switch cases to handle different types of errors.
Exception handling enables the programmer to handle the error at the most appropriate level, where traditional error handling often requires the error to be handled at the same level where it occurs.
In summary, exception handling is a technique that uses exceptions to handle errors and unexpected situations in a program, where traditional error handling uses return codes or status flags. Exception handling is more structured, easier to understand and can handle multiple types of errors with a single catch block, while traditional error handling requires multiple if-else statements or switch cases.
