[Punit Jain]

how to give more effects to image, i have a fish image, that is moving around the JFrame, and what i want also animation in fins of fish, how can i do this??
here is my code:-

import javax.swing.*;  

import java.awt.*;  
import java.awt.event.*;  
import java.util.Random;  
  
class Test {  
	public static void main(String args[])
	{ 
		JFrame frame = new JFrame();
		Cpoint point = new Cpoint();
		Cdynamic d = new Cdynamic(point);
		Cair ca= new Cair();
		d.panel.setBackground(Color.ORANGE);
        point.setBackground(new Color(0,0,255));
		JSplitPane sp = new JSplitPane(JSplitPane.VERTICAL_SPLIT, d.panel, point);
		Container c = frame.getContentPane();
	   	c.add(sp, BorderLayout.CENTER);
	   	ca.setPreferredSize(new Dimension(200,0));
	   	c.add(ca, BorderLayout.EAST);
	   	frame.setVisible(true);
		frame.setSize(1280,750);
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	 } 
}  
class Dynamic extends JPanel

  JButton button;  
  JLabel label;  
  Cpoint cp;
  Dynamic(Cpoint c)

    panel = new JPanel();  
    panel.setBackground(Color.yellow);  
    button = new JButton("Fish Die");

    panel.add(button);  
    panel.add(label);

just a thought only:

if you understand how cartoons are animated i.e. lots of drawings each drawn a little differently,
then shown in quick succession so the drawings appear to have movement, maybe if you can get
a slideshow (?) of images of a fish swimmming, then, as you move the fish position you also change
the image to the next one in the slideshow.
