How does an exception in a ‘finally’ block affect program flow?
Track: Java
Topic: Exceptions
Focus: try catch finally
Java: try catch finally
Answer
An exception in a 'finally' block can override exceptions from try or catch blocks.
If an exception is thrown within a 'finally' block, it can suppress any previous exceptions from the 'try' or 'catch' blocks. This can lead to confusion when debugging, as the original exception is lost. For example, in a file operation, if a 'finally' block attempts to close a file and throws an IOException, the original file processing exception might be obscured.
