Question

I was wondering if I could change this in any way so that I could have the output:

P1 Hand: 10 of diamonds, 9 of clubs, 5 of spades, Queen of spades, 4 of clubs.
P2 Hand: 7 of diamonds, 10 of spades, Jack of clubs, 6 of diamonds, 5 of clubs.
P3 Hand: 8 of spades, 8 of diamonds, 4 of spades, 3 of spades, 10 of hearts.
P4 Hand: Ace of spades, 8 of clubs, 6 of spades, Jack of spades, 3 of hearts.

NEVER have the same card in two different players. My code is here:

import java.util.Random;
import java.util.Arrays;
import java.util.ArrayList;

public class cardGame {
  public static void main(String[] args) {
    Random sad = new Random();
    ArrayList<String> all = new ArrayList<>(Arrays.asList("Ace of spades","2 of spades","3 of spades","4 of spades","5 of spades","6 of spades","7 of spades","8 of spades","9 of spades","10 of spades","Jack of spades","Queen of spades","King of spades","Ace of spades","2 of spades","3 of spades","4 of spades","5 of spades","6 of spades","7 of spades","8 of spades","9 of spades","10 of spades","Jack of spades","Queen of spades","King of spades","Ace of hearts","2 of hearts","3 of hearts","4 of hearts","5 of hearts","6 of hearts","7 of hearts","8 of hearts","9 of hearts","10 of hearts","Jack of hearts","Queen of hearts","King of hearts","Ace of diamonds","2 of diamonds","3 of diamonds","4 of diamonds","5 of diamonds","6 of diamonds","7 of diamonds","8 of diamonds","9 of diamonds","10 of diamonds","Jack of diamonds","Queen of diamonds","King of diamonds","Ace of clubs","2 of clubs","3 of clubs","4 of clubs","5 of clubs","6 of clubs","7 of clubs","8 of clubs","9 of clubs","10 of clubs","Jack of clubs","Queen of clubs","King of clubs"));
    ArrayList<String> trump = new ArrayList<>(Arrays.asList("spades","hearts","diamonds","clubs"));
    System.out.println("Boure hands and trump game.");
    System.out.println("");
    System.out.println("Trump: " + trump.remove(sad.nextInt(trump.size())) + ".");
    System.out.println("");
    System.out.println("P1 Hand: " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ".");
    System.out.println("");
    System.out.println("P2 Hand: " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ".");
    System.out.println("");
    System.out.println("P3 Hand: " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ".");
    System.out.println("");
    System.out.println("P4 Hand: " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ", " + all.remove(sad.nextInt(all.size())) + ".");
  }
}

BTW the duplicate didn't help in one way: It didn't include arrays, which is what I'm dealing with. With that stated, I couldn't look at the question and figure out where I can change.

Answer 1

Start off with a Deck of cards, and then assign the cards to each Player by removing them from the Deck and adding them to the Player 's Collection which models the Player 's Hand.

That way the player can only get the cards from the deck, and you can initialize the deck with one of each appropriate card.
