Exception Handling
About Exception Handling
Responding to undesirable or unexpected events that occur while a computer program is running is known as exception handling. Without this procedure, exceptions would interfere with a program's regular functioning and cause it to crash. Exception handling deals with these occurrences to prevent this from happening.
Runtime problems like ClassNotFoundException, IOException, SQLException, RemoteException, etc. may be handled using a process called exception handling.
Why is Exception Handling important?
When dealing with exceptions that cannot be handled locally, exception handling is helpful. The exception handler moves control to where the issue may be addressed rather than displaying an error status in the application. A function has the option of handling exceptions or throwing them. Java applications offer the following benefits over conventional error management methods when utilizing exceptions to handle errors:
- Dividing "regular" code from error handling code.
- Errors Spreading Up the Call Stack.
- Error Differentiation and Error Types are grouped.
