玫瑰花代码编程java

以下是一个使用Java编写的玫瑰花代码示例：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Rose extends JPanel {
    private static final long serialVersionUID = 1L;

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;

        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.setColor(Color.RED);

        int centerX = getWidth() / 2;
        int centerY = getHeight() / 2;

        int numPetals = 20;
        int petalRadius = 100;

        for (int i = 0; i < numPetals; i++) {
            double angle = i * 2 * Math.PI / numPetals;            int x = (int) (centerX + petalRadius * Math.cos(angle));
            int y = (int) (centerY + petalRadius * Math.sin(angle));
            g2d.fillOval(x, y, 10, 10);
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Rose Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        Rose rose = new Rose();
        frame.add(rose);
        frame.setSize(400, 400);
        frame.setVisible(true);
    }
}
