Checkstyle analyzes Java source code against configurable rules to enforce coding standards for naming, imports, formatting, Javadoc, and class design, among others. It enables teams to automatically enforce consistent coding practices by configuring rules, applying established style guides (Google Java Style, Sun Style, OpenJDK Style, Doc Style), and running checks to produce precise violation reports. It supports integration with build tools and IDEs, and allows extending with custom checks or writing filters and listeners for automated code quality.
