Multiple variables in one declaration

Reports multiple variables that are declared in a single declaration and suggest creating a separate declaration for each variable.

Some coding standards prohibit such declarations.

Example:

int x = 1, y = 2;

After the quick-fix is applied:

int x = 1; int y = 2;

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.

MultipleVariablesInDeclaration
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 | Code style issues

Configure the inspection:

  • Use the Ignore 'for' loop declarations option to ignore multiple variables declared in the initialization of a 'for' loop statement, for example:

    for (int i = 0, max = list.size(); i > max; i++) {}
  • Use the Only warn on different array dimensions in a single declaration option to only warn when variables with different array dimensions are declared in a single declaration, for example:

    String s = "", array[];
