cangjie-error-handle

Exception handling in Cangjie uses try-catch-finally blocks to intercept runtime errors. You wrap risky code in try, catch specific exception types, and use finally for cleanup. This prevents crashes and ensures predictable application behavior.

In Cangjie, Error and Exception types differentiate critical failures from recoverable runtime issues. The exception hierarchy separates them to ensure you catch specific exception types appropriately, making your application's error handling logic more robust and precise.

Option type error handling in Cangjie uses Option<T> or ?T for null-safe management. You handle missing values via pattern matching, ??, ?, and getOrThrow() instead of throwing exceptions, ensuring safer data handling without runtime crashes.

To define custom exceptions in Cangjie, create classes within the exception hierarchy. You instantiate and throw custom exceptions using the throw keyword within try blocks to handle specific application logic errors.

Try-with-resources in Cangjie manages resource cleanup automatically. By declaring resources within the try block, the runtime ensures they are closed properly, preventing leaks and simplifying error handling during runtime exceptions.

Cangjie supports common built-in runtime exceptions for robust application development. Listing these built-in exceptions helps developers understand the error type encountered and implement appropriate try-catch blocks to handle them effectively.
