What tools are available for automatic quality and error checking in source code?

Various static analysis and linting tools are used for automatic quality and error checking in source code. Here are some of them:

• SonarQube — a platform for continuous code analysis that detects bugs, vulnerabilities, and quality issues.
• ESLint — a popular linter for JavaScript that helps enforce style and find errors.
• Pylint — a tool for analyzing Python code.
• Checkstyle — checks Java code style.
• FindBugs / SpotBugs — a Java bytecode analyzer for potential errors.
• PMD — a static code analyzer for Java and other languages.

These tools integrate into the build and CI/CD process, automatically checking code during commits or project builds.
