Java gui animation 6 circles rotate code

Creating an animation with six rotating circles in Java can be a fun challenge! Here's an example using Java Swing that animates six circles rotating around a central point:

java

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class RotatingCirclesAnimation extends JPanel implements ActionListener {
    private Timer timer;
    private double angle = 0;
    private int radius = 100;
    private int numCircles = 6;
    private int circleDiameter = 50;

    public RotatingCirclesAnimation() {
        timer = new Timer(16, this); // Update every 16 milliseconds (60 FPS)
        timer.start();
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        int centerX = getWidth() / 2;
        int centerY = getHeight() / 2;

        for (int i = 0; i < numCircles; i++) {
            double theta = angle + (2 * Math.PI * i / numCircles);
            int x = (int) (centerX + radius * Math.cos(theta)) - circleDiameter / 2;
            int y = (int) (centerY + radius * Math.sin(theta)) - circleDiameter / 2;
            g2d.setColor(Color.getHSBColor((float) i / numCircles, 1.0f, 1.0f));
            g2d.fillOval(x, y, circleDiameter, circleDiameter);
        }
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        angle += Math.PI / 180; // Increment angle to rotate circles
        repaint();
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Rotating Circles Animation");
        RotatingCirclesAnimation animation = new RotatingCirclesAnimation();
        frame.add(animation);
        frame.setSize(800, 600);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}

In this code:

• The RotatingCirclesAnimation class extends JPanel and implements ActionListener.

• A Timer is used to update the angle every 16 milliseconds, creating a smooth 60 FPS animation.

• The paintComponent method calculates the positions of six circles based on the angle and draws them.

• The actionPerformed method updates the angle to rotate the circles and repaints the panel.

• The main method sets up the JFrame and adds the animation panel to it.

Feel free to experiment and customize the code to suit your needs. Enjoy creating your animation! If you have any more questions or need further assistance, I'm here to help.
