Java Error-as-Value Pattern

소개

This skill integrates the Result pattern into Java applications, providing a functional approach to error handling inspired by Rust and Haskell. By treating errors as explicit values rather than exceptions, it enables type-safe operations, eliminates hidden control flows, and allows for seamless functional composition through monadic chaining. It is an ideal solution for developers building robust APIs, implementing validation pipelines, and refactoring legacy try-catch blocks into clean, predictable, and performant code that leverages modern Java features like sealed interfaces and records.
