Exception Handling Flow
- Try Block Execution: The code within the try block is executed.
- Exception Occurrence Check: If an error or exception occurs during the execution of the try block, it’s caught.
- Catch Block Execution: Control moves to the corresponding catch block, where the exception is handled.
- Finally Block Execution: Regardless of whether an exception occurred or not, the code within the finally block is executed.
- Propagation: If the exception cannot be handled in the catch block, it propagates up the call stack.
- Higher-Level Handling: The exception may be caught and handled by higher-level code or the default handler.
- Cleanup: Finally, any cleanup tasks specified in the finally block are executed before the program continues its normal flow of execution.
Finally Block in Programming
The finally
block in programming, commonly used in languages like Java and C#, is a block of code that is executed regardless of whether an exception is thrown or not. It is typically used in conjunction with a try-catch
block to ensure certain cleanup or finalization tasks are performed, such as closing resources like files or database connections.
