handling display flow errors gracefully with fault paths

in user interfaces, displaying information (the "display flow") is a critical aspect of user experience. however, various issues can arise during this process, leading to errors and potentially frustrating the user. common scenarios include:

*data retrieval failures:* attempting to fetch data from a database or external api, but the request fails due to network issues, server errors, or invalid credentials.
*data transformation errors:* trying to convert data from one format to another (e.g., parsing json, converting dates), but encountering malformed data or unexpected values.
*rendering errors:* problems rendering ui elements, like image loading failures, or template parsing errors.
*authorization issues:* the user lacks the necessary permissions to view specific data or features.
*unexpected edge cases:* data inconsistencies or unexpected data values leading to logic errors during the display process.

a robust error handling strategy is crucial to ensure a smooth user experience, even in the face of these issues. *fault paths* provide a structured approach to handle errors and exceptions that may occur during the display flow, allowing you to gracefully recover and provide meaningful feedback to the user.

*key concepts*

*exception handling:* catching and managing exceptions that disrupt the normal flow of execution. this prevents crashes and allows for controlled error recovery.
*try-catch-finally blocks:* a fundamental construct for exception handling. the `try` block encapsulates the code that might throw an exception. the `catch` block specifies how to handle specific exception types. the `finally` block (optional) contains code that is always executed, regardless of whether an exception occurred or not (useful for cleanup).
*fault paths (error handling paths):* alternative execution paths designed to handle errors. these paths often involve l ...
