Inspectopedia Help

Overly complex class

Reports classes whose total complexity exceeds the specified maximum.

The total complexity of a class is the sum of cyclomatic complexities of all the methods and initializers the class declares. Inherited methods and initializers are not counted toward the total complexity.

Too high complexity indicates that the class should be refactored into several smaller classes.

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Class metrics
