public class LocalFinalVariableNameCheck
extends AbstractNameCheck

Checks that local final variable names conform to a format specified by the format property. A catch parameter is considered to be a local variable.The format is a regular expression and defaults to ^[a-z][a-zA-Z0-9]*$.

An example of how to configure the check is:

 <module name="LocalFinalVariableName"/>
 

An example of how to configure the check for names that are only upper case letters and digits is:

 <module name="LocalFinalVariableName">
    <property name="format" value="^[A-Z][A-Z0-9]*$"/>
 </module>
