The exception translation pattern cleans up APIs, enforces robust error handling, hides internal complexity, and aligns code with domain logic.
A typical case of exception handling is demonstrated when dealing with I/O methods, involving tiers of low-level I/O, application logic, and application caller.
The visual diagram shows the flow of control and exceptions in the exception translation pattern.
Exception translation in Java is considered a best practice, encapsulating implementation details, improving clarity in error messages, providing a consistent error handling API, offering stronger compile-time guarantees, enabling flexibility in changing internal implementations, and encouraging domain-driven design.
