Question

My code is supposed to do the following:

-Display a frame containing 3 cards

-Each card is to be selected randomly from the list of card images given.

I have written this code and get 3 cards/images, but do not know how to make them into an array list so that they will be selected randomly instead of being assigned.

If someone can please re-write my code into a complete compilable code that works. Including an array list so that my cards are selected randomly, I will give full rating.

My code thus far:

import javax.swing.*;

import java.awt.*;

public class Cards extends JFrame

{

   public static void main (String[] args)

   {

   Cards frame = new Cards();

   frame.setTitle("Cards");

   frame.setSize(300,200);

   frame.setLocationRelativeTo(null);

   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   frame.setVisible(true);

   }

      private ImageIcon Card1 = new ImageIcon("C:/Users/Public/Pictures/card/14.png");

      private ImageIcon Card2 = new ImageIcon("C:/Users/Public/Pictures/card/15.png");

      private ImageIcon Card3 = new ImageIcon("C:/Users/Public/Pictures/card/16.png");

  

public Cards()

{

   setLayout(new GridLayout(1,4,5,5));

   add(new JLabel(Card1));

   add(new JLabel(Card2));

   add(new JLabel(Card3));

}

}

Explanation / Answer

public [More ...] ArrayList(Collection<? extends E> c) {



         elementData = c.toArray();



         size = elementData.length;


         // c.toArray might (incorrectly) not return Object[] (see 6260652)



         if (elementData.getClass() != Object[].class)



             elementData = Arrays.copyOf(elementData, size, Object[].class);



     }
