How can I implement custom exceptions in deserialization?

You can create a custom exception class that extends the base exception class in your programming language. Then, during the deserialization process, you can throw this custom exception when you encounter specific errors.

Can you give me a code example of that?

Sure! In Python, you might define a custom exception like this:

class DeserializationError(Exception):
    pass

# During deserialization
if some_condition:
    raise DeserializationError('Failed to deserialize the object.')

What about in Java? Is it similar?

Yes, in Java, you would create a custom exception like this:

public class DeserializationException extends Exception {
    public DeserializationException(String message) {
        super(message);
    }
}

// During deserialization
if (someCondition) {
    throw new DeserializationException("Failed to deserialize the object.");
}

Thanks! How do I handle these exceptions when they occur?

You can handle these exceptions using try-catch blocks. For example:

try {
    // deserialization code
} catch (DeserializationException e) {
    System.out.println(e.getMessage());
}
