This provides a business-friendly metric to justify refactoring. For Java teams, this is often missing—SonarQube has similar concepts, but NDepend’s model is more transparent and customizable.

Modern Java uses heavy lambdas and streams ( map , filter , collect ). Because the Java compiler generates synthetic methods for lambdas, NDepend’s bytecode reader may count these synthetic methods as separate "methods," slightly inflating complexity metrics. NDepend has filters for synthetic members, but you may need to tweak them. Because the Java compiler generates synthetic methods for
