Java写一个动态樱花树代码

在Java中创建一个动态的樱花树动画，我们通常会利用Swing或JavaFX这样的图形用户界面库来构建。这里提供一个简单示例，使用Swing库来创建一个基本的樱花树动画。请注意，这只是一个基础版的代码，实际效果可能会包含更多的细节和交互。

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Ellipse2D;
import java.util.Random;

public class SakuraTree extends JPanel {
    private static final int MAX_BLOOMS = 200;
    private Random random = new Random();
    private Ellipse2D.Double[] blooms;

    public SakuraTree() {
        setSize(600, 400);
        setFocusable(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setPreferredSize(new Dimension(600, 400));
        blooms = new Ellipse2D.Double[MAX_BLOOMS];
        for (int i = 0; i < MAX_BLOOMS; i++) {
            bloom(i);
        }
    }

    private void bloom(int index) {
        blooms[index] = new Ellipse2D.Double(
                random.nextDouble() * getWidth(),
                random.nextDouble() * getHeight(),
                10,
                20
        );
        repaint();
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setPaint(Color.WHITE);
        for (Ellipse2D.Double bloom : blooms) {
            if (bloom.width > 0 && bloom.height > 0) {
                g2d.draw(bloom);
            }
        }
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            JFrame frame = new JFrame("Dynamic Sakura Tree");
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.add(new SakuraTree());
            frame.pack();
            frame.setVisible(true);
        });
    }
}
