Utility Core Documentation
(1) Introduction
This Java library serves as a comprehensive toolkit designed to significantly enhance developer productivity by addressing the common challenges of boilerplate code and inherent Java limitations.
In addition, the library overcomes several of Java's limitations by offering enhanced features for complex tasks like reflection and functional programming, along with robust solutions for immutability. By abstracting away the tedious and verbose parts of standard Java development, it enables developers to focus on core application logic, ultimately speeding up development cycles and improving overall code quality.
(2) Implementation
The Utility Core library provides a set of utility classes intended to streamline development by reducing boilerplate code and enhancing code readability. By offering reusable functions and tools, the library helps you perform common tasks more efficiently. The examples showcase how you can integrate these utilities into your project to save time and effort, making your code more concise and maintainable. Additionally, a JavaDoc has been created to further assist in understanding and using the utilities effectively.
(2.1) Stream Utility
The Stream Utility is a powerful helper for working with the Java Stream pipeline, offering two key enhancements. First, it provides a clean way to handle checked exceptions within stream operations, eliminating the need for verbose try-catch blocks and making the code more readable and maintainable. Second, it adds index management capabilities, allowing developers to access the index of elements while processing streams. This is particularly useful in scenarios where operations depend not just on the value but also on the position of the element in the stream. Together, these features make stream-based programming in Java more expressive and convenient.

(2.2) Optional Utility
The Optional Utility is a powerful helper for working with the Java Optional class, offering two key enhancements. First, it offers built-in support for handling checked exceptions gracefully within optional operations, removing the clutter of manual try-catch blocks and resulting in cleaner and more maintainable code. Second, it introduces index management capabilities, allowing developers to access the position of elements within a processing context—particularly useful when Optionals are derived from indexed sources or sequences. These enhancements empower developers to write more expressive and streamlined code when working with Optionals in Java.

(2.3) Functional Utility
The Functional Utility enhances Java’s core functional interfaces by adding two key capabilities. First, it simplifies exception handling by effortlessly supporting checked exceptions in lambda expressions, eliminating the need for boilerplate try-catch blocks. Second, it introduces index-aware variants of standard functional interfaces, allowing developers to access the position of elements during functional processing. These enhancements make Java’s functional programming approach more adaptable, intuitive, and capable of addressing complex processing needs.

(3) Installation
You can include the following dependency from the Maven Central Repository, which is a widely used public repository for Java libraries. It is compatible with all major Java build tools. so there's no need to download or manage the library manually—your build tool will automatically fetch and include it during the build process.
