A static analysis toolset for Java code

QA∙J combines three highly-regarded open source tools for analyzing Java code: Checkstyle, FindBugs and PMD. Together, these have nearly 1000 checks. The tools are integrated into a common framework, making them easy to configure and use.

QA∙J works under the same runtime framework as QA∙C and QA∙C++. This gives consistency of use across languages. Common result formats means that data from all the tools is handled seamlessly by all downstream components such as the QA∙Verify results analysis and distribution tool.

QA∙J detects and reports on reliability problems, maintainability issues and coding standard violations quickly and efficiently. By adhering to the “early & often” philosophy, software defects are identified at creation resulting in simplified development lifecycle and reduced costs and cycle time. QA∙J provides an efficient, robust, and fully automated environment to introduce
and enforce coding standards.



  • Analyzes Modern Java language features
  • Identifies coding defects at the earliest possible stage in the development cycle
  • Improves code reliability, maintainability, portability, re-usability and testability
  • Provides an efficient, robust, fully automated environment to introduce and enforce custom coding standards
  • Incorporates advanced message suppression
  • Diagnostics, configurable metric thresholds to limit code complexity
  • Automated code inspection provides instant, objective, repeatable code audits
  • Accelerates and refocuses the code review process and improves teamwork
  • Uses three well-regarded open source tools to provide the checks
  • The open source tools are seamlessly integrated into a common framework for ease-of-use
