Remove object from 1 arraylist and add to another

Question

I'm really hoping I can convey my intentions here:

I have a class called ("Branch") (I believe it is called an Object) and I have 2 instances of branches.

Basically (in my main class):

    private static Branch branch1 = new Branch();
    private static Branch branch2 = new Branch();

I know how to (on a basic level) add to a branch and how to remove from branch1.

(in my Branch class file):

    public void addPet(VirtualPet pet) {
        pets.add(pet);
    }

    public void removePet(String name) {
        for (int i = 0; i < pets.size(); i++) {
            if (pets.get(i).getName().equals(name)) {
                pets.remove(i);
            }
        }
    }

These work fine. But I'm trying to do a transfer from 1 branch to another branch (ex: branch1 to branch2).

I figure my removePet method would be the same, but I'm wondering how do I add that pet to the other branch? I know how to add a completely new pet, but I'm not sure how to pull the data from the pet I'm deleting and use that to add the new pet.

Answer 1

The answer is simple, return remove the item and add to the other branch

// return the pet
public VirtualPet removePet(String name) {
        for (int i = 0; i < pets.size(); i++) {
            if (pets.get(i).getName().equals(name)) {                
                return pets.remove(i); // API  https://docs.oracle.com/javase/8/docs/api/java/util/List.html#remove-int-
            }
        }
        return null;
    }

// then you can add this to other object
VirtualPet pet = branch1. removePet("something");
if (pet != null) {
    branch2.addPet(pet);
}
