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:
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.
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.
