What is the need of Exception Handling?
Exception handling plays an essential role in writing robust code and reliable software. It provides a mechanism for dealing with unexpected situations and errors. It is used to handle errors and other exceptional situations gracefully. It allows the program to respond appropriately rather than crashing or producing incorrect results. Exception handling involves
- Detecting when an exception occurs (Try block).
- How to handle it (Catch block).
- How to recover from it.
