Software Notes from Underground

Introduction Throughout my career as a Java developer, I've frequently implemented a particular pattern across numerous projects. This pattern, known as the operation result pattern , encapsulates the outcome of an operation along with its return object, enhancing code clarity. It distinctly categorizes function call outcomes into success or failure, each requiring appropriate handling by the developer. In contrast, certain languages, such as Kotlin, integrate this pattern within their standard libraries, or like Golang, facilitate the return of additional information to indicate the operation's outcome. Unfortunately, Java lacks such a built-in solution, prompting the need for a standardized approach. Motivated by this gap, I created a library that implements the result pattern in the JResult , a library aimed at brining the operation result pattern in Java applications.

Throughout my journey in various Java projects, I've consistently encountered the need to reimplement a specific pattern — one that encapsulates the results of operations without resorting to exceptions, such as during input validation.  This pattern, known as the Operation Result Pattern, may not be universally recognized as a formal design pattern, but in my experience, it's an incredibly useful approach for handling operation outcomes. I thought it would be nice to have it in a form of a simple library that can be easily integrated in the Java projects. After dedicating a few weeks to development, I'm excited to announce the release of the first version of this library, which I've named JResult.  It's designed to be lightweight, easy to use, and flexible enough to accommodate various project needs.
