Apache Commons - Beyond StringUtils
summary
Overview of specific reusable pieces beyond StringUtils: shows concrete use of Commons Lang for null‑safe constructors, String/array helpers and type conversion; uses Commons Configuration to merge system, file and OS‑specific properties; builds a working command‑line tool with Commons CLI demonstrating short/long options, help and parsing; uses Commons IO/streaming readers to solve pathological split and CSV cases and BeanUtils for mapping text to objects. Demos compile and run, reduce boilerplate and fix real edge cases like tricky splitting and cross‑Java compatibility.
