If multiple different exception classes can be thrown in the code, how should the handling be structured?

When different exception classes can occur in the code, the handling should be built considering the hierarchy of exceptions and the specifics of each error.

It is recommended to:

• Use multiple catch blocks, starting with the most specific exceptions and ending with more general ones.
• Handle each error appropriately in each catch (logging, recovery, re-throwing).
• Use a general catch for unforeseen exceptions if necessary.

Example:

try {
    // code that may throw different exceptions
} catch (FileNotFoundException e) {
    // handle file not found error
} catch (IOException e) {
    // handle other input-output errors
} catch (Exception e) {
    // general handler for all other exceptions
}

This approach allows precise response to different errors and maintains code clarity.
