Java Playground

Personal sandbox for exploring Java language features and libraries.

Advent of Code inputs

• Puzzle inputs are not tracked in git (src/test/resources/advent*/** is ignored).
• Advent 2025 tests auto-download inputs locally using AOC_SESSION (session cookie) and AOC_USER_AGENT; downloads are blocked on CI and those tests are JUnit-disabled when CI/GITHUB_ACTIONS is set.
• Suggested user agent: java_playground/2025 (maintainer: you@example.com).
