Code Quality uses the following CodeQL queries to analyze Java code and detect code quality issues on:

Your default branch, with results shown on the repository's "Standard findings" dashboard
Pull requests, with findings shown as comments made by github-code-quality[bot]

Copilot Autofix suggestions are provided for findings where possible.
