how to add images dynamically to jpanel?

[Punit Jain]

hello, i added some images to jpanel, with some animation.
i put some images in a folder, and i m display/moving them on jpanel simultaneously.
my question is can i add images dynamically??
i mean what i want is, i want to add a button on that panel, and when i click on that button, one more image (randomly) should added to my jpanel from that folder.
how can i do this??

the code to add the image is identical to
how you'd add it when the frame first opens.

because the frame is now visible, after
adding it you need to have these lines

panel.add(image);//however you add it
panel.revalidate();
panel.repaint();

but how even i add add those images on button click one by one, i mean how i get images randomly from my image folder??

fish1 = new Cfish(5,10, new ImageIcon("d:\\fish\\fish1.png").getImage());
		fish2 = new Cfish(100,300, new ImageIcon("d:\\fish\\fish2.png").getImage());	
		fish5 = new Cfish(500,10, new ImageIcon("d:\\fish\\fish5.png").getImage());
		fish6 = new Cfish(300,600, new ImageIcon("d:\\fish\\fish6.png").getImage());
		fish7 = new Cfish(820,70, new ImageIcon("d:\\fish\\fish7.png").getImage());
		fish9 = new Cfish(90,275, new ImageIcon("d:\\fish\\fish5.png").getImage());
		fish10 = new Cfish(90,50, new ImageIcon("d:\\fish\\fish2.png").getImage());

above is what i am doing right now.

you need to use Math.random()
check the API and tutorials

Or java.util.Random

another option, at program startup, is to load them all into a List,
then Collections.shuffle(list) and add them to your panel in the
'shuffled' order of the list.
