Java = Return a list of objects / array or result-object (same as method parameters)

This may seem like a strange question: I am struggling to decide whether it is good practice and to “work effectively” with “typed objects” at a very narrow level.

public Object[] doSomething() {
    Object[] resultList = new Object[] {new Foo(), new Bar()};
    return resultList;
}

against

public Result doSomething() {
    Result result = new Result();
    result.foo = new Foo();
    result.bar = new Bar();
    return result;
}

public class Result{
    Foo foo;
    Bar bar;
}

My question is specific:

  • In terms of CPU cycles (as a relative figure), how much of the second approach consumes more resources. (e.g. 100% more)

  • Same question regarding memory consumption

NB (these two questions, to understand this more, and not about premature optimization)
