When multiple exception types are defined in the Catch block, which block executes for an exception matching two types?

When multiple exception types are defined in a Catch block, the block that corresponds to the most specific match for an exception is the one that executes. This means that if an exception thrown matches more than one type defined in the Catch blocks, the runtime system will look for the most precise or specific exception type first. The most specific match is prioritized because it is generally more informative for handling the exception appropriately.

For example, if there are multiple catch blocks for a general exception type and a more specific exception type derived from it, and an exception occurs that is an instance of the derived class, the catch block corresponding to that derived exception will execute. This behavior ensures that the unique handling of specific exceptions can be implemented without being overshadowed by more general exception handling, thus allowing for more tailored and effective error management.
