Inspectopedia Help

Overly complex boolean expression

Reports boolean expressions with too many terms. Such expressions may be confusing and bug-prone.


cond(x1) && cond(x2) ^ cond(x3) && cond(x4);

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 | Control flow issues

Configure the inspection:

  • Use the Maximum number of terms field to specify the maximum number of terms allowed in a boolean expression.

  • Use the Ignore pure conjunctions and disjunctions option to ignore boolean expressions which use only a single boolean operator repeatedly.
