Assigning two arrays by ID

Question

I am in stuck with easy things such a loop for and if statement.

I have two different objects:

objectA:

0: id = 1, name = null

1: id = 3, name = null

objectB:

id = 1, name = NameForID1

id = 3, name = NameForID3

My point is to assign names from objectB to objectA by ID value.

I've done double loop + if:

            for (int i = 0; i <= objectA.size() - 1; i++){
                for(int j = 0; j<=objectB.size() - 1; j++){
                    if(Objects.requireNonNull(objectA.get(i).getobjectAID()).equals(objectB.get(j).getObjectBID()))
                        objectA.get(i).setobjectAName(objectB.get(j).getobjectBName());
                }
            }

And after this I have a list of objectA with last name from objectB array. According to Android Studio Debugger and some... logic... this is logically, but what I am missing and doing wrong?

My bad output:

objectA:

0: id = 1, name = NameForID3

1: id = 3, name = NameForID3

Expected output:

objectA:

0: id = 1, name = NameForID1

1: id = 3, name = NameForID3

UPD

ObjectA class:

class objectA:Serializable {
    var objectAID: Int? = null
    var objectAName: String? = null
}

ObjectB class:

class objectB {

    var objectBName: String? = null
    var objectBID: Int? = null

}

UPD. 30.04.2020: Still getting the same bad output, based on answers below have tried different variations of equals, ==, ===, POJO in Java instead of Kotlin.

UPD: Just wasted your time - when I was trying to found error with your hints, I have malwared my code and started assigning equal IDs to objectA so and names were equal.

Answer 1

I am assuming that the ids are integers:

Try this:

for (int i = 0; i < objectA.size(); i++){

for(int j = 0; j < objectB.size(); j++){

if(objectA.get(i).getobjectAID() == objectB.get(j).getObjectBID()){

//set
objectA.get(i).setobjectAName(objectB.get(j).getobjectBName());

}

}

}

Your POJO must be in java like this:

Object A

public class objectA {
    private int objectAID;
    private String objectAName;

    //generate getters and setters........
}

Object B

public class objectB {
    private int objectBID;
    private String objectBName;

    //generate getters and setters........
}
