Underscore-java

Provides method chaining for operations like filter, map, and sort, enabling concise code as shown in examples such as U.of(1,2,3).filter(v -> v > 1).map(v -> v + 1).

Includes utilities for formatting, parsing, and converting between XML and JSON, demonstrated with functions like U.formatXml and U.jsonToXml in the README.

Offers object and array builders to programmatically construct complex JSON and XML documents, as illustrated in the U.Builder example.

Ports Underscore.js functionality with matching unit tests, ensuring reliability and consistency for developers familiar with JavaScript.
