Question

Need to add this stuff into the Java code that is pasted in bold .

Textbox to allow the user to enter the number of cards they want to display (1-54)

Button to generate random cards based on the number entered by user. Can be clicked multiple times within the same session to regenerate the cards.

Base the number of rows/columns on how many cards are shown

Place the textbox/button at the top of the frame and have the cards show below them.

package Cards;

import javax.swing.*;

import java.awt.*;

import java.util.*;

import java.awt.event.*;

public class Cards {

public static void main (String [] args)

{

   int min = 1, max = 54;

   JFrame frame = new JFrame ("Cards");

   frame.setTitle("Cards");

   frame.setSize(310,150);

   frame.setLayout(new FlowLayout(FlowLayout.LEFT, 2, 2));

   Random rand = new Random();

   for (int x = 0; x < 3;x++)

      {

       int randomNum = rand.nextInt((max - min) + 1) + min;

       frame.add(new JLabel(new ImageIcon("card/" + randomNum + ".png")));

      }

   frame.pack();

   frame.setVisible(true);

   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   }

}

Cards.java

package Cards;

import java.awt.*;
import java.util.*;
import java.awt.event.*;

public class Cards extends JFrame implements ActionListener{
   //assuming each card image width = 50; I used this to base number of columns for the frame; set this value according to the width of card images
   // assuming each card image height = 500;hoping that this image can fit in this frame without any problem.
   //all I need too do is change width of frame based on number given in text field.
   // frame width = number in textfield * Image width,i.e 50, in this case;
  
   int imageWidth = 50;
   int imageHeight = 500;
