我在 sonarqube 中测试了以下方法，收到消息说重构此方法以将其认知复杂度从允许的 32 降低到 15

Question

如何将下面的方法分开，将一个方法调用给另一个方法。

public static void dissociateRouteRecordsFromCreditApplication(List creditAppList,Map oldCAMap){ final String pendingSTR = 'Pending'; 设置 setOfCreditApplicationIdForNewCollateral = new Set(); 设置 setOfAppPurposesNewCollaterals = new Set(Label.appPurposeNewCollaterals.split(',')); 设置 setOfCreditApplicationIdForQIandILC = new Set(); 设置 setOfAppPurposesQI = new Set(Label.appPurposeQI.split(',')); 设置 setOfAppPurposesILC = new Set(Label.appPurposeILC.split(',')); 设置 setOfCreditApplicationIdsForScripts = new Set(); 设置 setOfAppPurposesScripts = new Set(Label.appPuporseScripts.split(',')); Map mapOfCreditAppIdToTypeOfQI = new Map(); Map mapOfCreditAppIdToTypeOfILC = new Map(); 列表 listOfDissociationRecordsToBeUpdated = new List();

for(LLC_BI__Product_Package__c creditApp : creditAppList){
