What is the role of the finally block in exception handling?

The finally block in exception handling serves the specific purpose of containing code that must execute regardless of whether an exception was thrown or caught. This ensures that essential cleanup actions—such as closing file streams, releasing resources, or resetting states—are performed.

No matter if an exception occurs in the try block or if it is handled in the catch block, the finally block will always run before the control exits the try-catch structure. This feature is particularly useful for maintaining resource integrity and ensuring that necessary code is executed, which is important for preventing resource leaks and ensuring consistent application behavior.

Other options do not correctly describe the role of the finally block. The first option suggests that it prevents exceptions, which is not accurate since it does not stop exceptions from occurring. The second option implies that the finally block is used to catch exceptions, while catching is typically the purpose of the catch block. The last option states that it is for initializing variables, which is not relevant to the function of the finally block in exception handling.
