### Question:
CheckstyleFormatImporterWithRuleLoader extends CheckstyleFormatImporter { @Override protected Severity severity(String ruleKey, @Nullable String severity) { return externalRuleLoader.ruleSeverity(ruleKey); } CheckstyleFormatImporterWithRuleLoader(SensorContext context, String linterKey, ExternalRuleLoader externalRuleLoader);   }### Answer:
