Java: Custom Exceptions
Answer
It organizes exceptions into a logical structure, allowing for more specific error handling.
Designing a hierarchy lets you group exceptions logically, making it easier to catch specific errors. For instance, in an e-commerce system, you might have `PaymentException` as a parent class, with `InvalidPaymentException` and `PaymentTimeoutException` as subclasses, allowing different handling for each.
