Help with Random cards

[carl]

Hi, I would like to display random images in a java applet i am doing. I have to create a card game called 'snap'. I would like 2 random cards to appear on the applet every time the 'Next' button is pressed which i will be creating.
This is the skeleton program i was given to start this program.,

Code:

import java.applet.*;
import java.awt.event.*;
import java.awt.*;

public class CardGame extends Applet implements ActionListener /*NB other interfaces may be added*/
{
int MAX= some_value;
MyObj myObjects[];

public void start()
{
myObjects=new MyObj[MAX];

//instantiate objects here
myObjects[0]=new MyObj(/*some_arguments*/);
}

public void actionPerformed(ActionEvent e)
{
}

public void paint(Graphics g)
{
}
}

class MyObj {
MyObj(/*some_arguments*/) {
}
}

Thanks.
