This project provides a modular Java implementation of the Beta function B(x,y) for positive integer arguments. It includes:

• CLI (BetaText) and Swing GUI (BetaGUI)
• Core logic (BetaCalculator, FactorialUtil) using BigInteger/BigDecimal
• Unit tests (JUnit 5)
• Static analysis (Checkstyle / PMD) and debugging evidence (JDB)
• Accessibility basics (label associations, tooltips, mnemonics)
• Semantic versioning and public GitHub hosting

Requirements

• Java SE 21 or higher
• Maven 3.9+
• Internet connection for dependency resolution
