What is the best way to get this attributes, thinking in performance and code quality?

Using chained calls:

    name = this.product.getStock().getItems().get(index).getName();
    id = this.product.getStock().getItems().get(index).getId();

Creating new variable:

    final item = this.product.getStock().getItems().get(index);
    name = item.getName();
    it = item.getId();

I prefer the second way, to let the code cleaner. But I would like to see some opinions about it.

Thank you!
