BPOOR combine two lists with different fields into one list
I have two lists with two different different fields to update the asset object in Salesforce. Below is the sample data.
When I merge them into one list, I get an exception during the update as the list has duplicate ids in it (a2i2, a2i3). I would like to merge both lists into one, but having both fields in the list as shown above.
Since the lists contain Ids, I can convert them into two maps and loop thru the first map using KeySet() and check if the Id is present in the second map. If it is available, I can populate field2. But I need to repeat the same with map2.
Is there a better approach for this?
List1: ==== AssetId Field1 a2i1 abc a2i2 acb a2i3 cad a2i4 gfd List2: ==== AssetId Field2 a2i0 mnp a2i2 nop a2i3 mnh a2i7 pqr a2i8 iyo Expected Output List: ================== AssetId Field1 Field2 a2i0 mnp a2i1 abc a2i2 acb nop a2i3 cad mnh a2i4 gfd a2i7 pqr a2i8 iyo

You can create a map like MAP<Id, NAME_OF_OBJECT> then iterate over both the list and check if the map contains id then use the instance and if not then add the instance.
Please mark this as the best answer if it helps.

There will be only one map, you will have to iterate both the list or combine both the list and iterate. The TC will be 0(n) only.
If you can post your code here so that I can look and see what you have done and will try to optimize it.
