Convert for loops with Lists into Maps
Hello All,
I would like to update my exsiting code that uses Lists to instead use maps.
Here is what I have:
I am trying to convert the above to use maps but I am not sure on how to compare the fields between teh 2 maps:
I would like to update my exsiting code that uses Lists to instead use maps.
Here is what I have:
List<object1__c> records1 = new List<object1__c>(); List<object2__c> records2 = new List<object2__c>(); records1 = [SELECT id, name from object1__c ]; records2 = [SELECT id, name from object2__c]; Object3__c result1 = (Object3__c ) so; if(!records1.isEmpty() && !records2.isEmpty()){ for (object1__c rec: records1) { for(object2__c rec2: record2) if (rec.Apple__c == rec2.Pear__c){ rec.Job_Item__c = result1.Id; } } }
I am trying to convert the above to use maps but I am not sure on how to compare the fields between teh 2 maps:
Map<Id,object1__c> records1 = new Map<Id,object1__c>(); Map<Id,object2__c> records2 = new Map<Id,object2__c>(); Object3__c result1 = (Object3__c ) so; if(!records1.isEmpty() && !records2.isEmpty()){ for(object1__c rec1 : records1.values()){ if (rec1.Apple__c = records2.get(Pear_c)){ rec1.Test__c = result1.Id; } } }
Please find the your solution:
Map<Id,object1__c> records1 = new Map<Id,object1__c>();
Map<Id,object2__c> records2 = new Map<Id,object2__c>();
Object3__c result1 = (Object3__c );
if( !records1.containsKey() !=null && !records2.containsKey() !=null ){
for( object1__c rec1 : records1.values() ) {
if (rec1.Apple__c = records2.get(Pear_c) ) {
rec1.Test__c = result1.Id;
}
}
}
Hope this helps, If you find your solution please mark it as the best answer.
Thanks
