Local variable naming convention

Reports local variables whose names are too short, too long, or do not follow the specified regular expression pattern.

A quick-fix to rename such variables is available only in the editor.

Example:

int X = 42;

This example will be reported if the inspection is enabled with the default settings where a variable name should start with a lowercase letter.

Locating this inspection

By ID

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

LocalVariableNamingConvention
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 | Naming conventions

Use the fields in the Options section to specify the minimum length, maximum length, and regular expression for acceptable local variable names. Specify 0 in a length field to skip the corresponding check. Regular expressions use the standard java.util.regex format.

Use the checkboxes to ignore for-loop parameters, catch-section parameters, and pattern variables.
