This is where students often get tripped up. Instead of physically removing a Card object from an ArrayList (which is computationally expensive), the Elevens Lab uses a variable called size to keep track of the "top" of the deck.
The AP Computer Science A is a classic "Big Idea" activity designed to teach object-oriented programming (OOP) through the creation of a solitaire-style card game. Activity 3 is a pivotal moment in the lab where you transition from managing individual cards to handling a collection of them: the Deck class .
