- **Type Safe** - Comprehensive use of generics and modern Java type system features

### Additional Components
- **Text Processing** (`org.codelibs.core.text`) - JSON utilities, tokenization, decimal formatting, and text manipulation
- **Logging Abstraction** (`org.codelibs.core.log`) - Flexible logging system supporting JCL (Jakarta Commons Logging) and JUL (Java Util Logging)
