How To Add In Arraylist Of Object

I'm creating a card game assignment... so i have an arraylist called cards that has 20 cards and every card has contains 2 objects, suit and the point Value.

I shuffled the deck, now i want to add half of it to player 1 and the rest of the cards goes to the bot or computer.

how can i add the cards to the player one arraylist and have all the information of the cards?

here is my Deck class code :-

public class Deck {
private ArrayList cards;
private int size;
private ArrayList player1;
private ArrayList bot;

[code]....

the problem i have is this one doesn't work

size = cards.size() / 2;
for (int i = 0; i < size - 1; i++) {
player1.add(cards.get(i));
}
for (int s = size; s < cards.size() - 1; s++) {
bot.add(cards.get(s));
}
