java-error-as-value

What problem does it solve?

Java traditionally relies on exceptions for error handling, which can obscure control flow and complicate maintenance. This Skill introduces a Result<T, E> type to treat errors as explicit values, enabling clear propagation of failures and safer, more predictable code paths.

Core Features & Use Cases

• Type-safe errors and explicit error flow with Ok/Err separation.
• Functional-style composition using andThen, map, and match to chain fallible operations.
• Easy refactoring of exception-based code and design of explicit, well-typed APIs.
• Real-world scenarios include input validation, configuration parsing, HTTP calls, and database interactions.

Quick Start

Copy assets/Result.java into your project and start returning Result values from methods.
