java编写炫酷圣诞树代码

以下是一个简单的Java代码示例，用于绘制一个炫酷的圣诞树：

import javax.swing.*;
import java.awt.*;

public class MyPanel extends JPanel {
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        drawTree(g, getWidth() / 2, getHeight() - 50, 100, 200);
    }

    private void drawTree(Graphics g, int x, int y, int width, int height) {
        g.setColor(new Color(34, 139, 34)); // 设置树的颜色为绿色

        // 绘制树干
        int trunkWidth = width / 5;
        int trunkHeight = height / 5;
        int trunkX = x - trunkWidth / 2;
        int trunkY = y - height;
        g.fillRect(trunkX, trunkY, trunkWidth, trunkHeight);

        // 绘制树冠
        int[] triangleX = {x - width / 2, x + width / 2, x};
        int[] triangleY = {y, y, y - height};
        g.fillPolygon(triangleX, triangleY, 3);

        // 绘制装饰品
        g.setColor(Color.RED); // 设置装饰品的颜色为红色
        g.fillOval(x - 10, y - height - 30, 20, 20); // 绘制一个圆形装饰品
        g.setColor(Color.YELLOW); // 设置装饰品的颜色为黄色
        g.fillRect(x - 5, y - height - 40, 10, 40); // 绘制一个长方形装饰品
    }
}

public class MyFrame extends JFrame {
    public MyFrame() {
        setTitle("炫酷圣诞树");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 400);
        setLocationRelativeTo(null);

        MyPanel panel = new MyPanel();
        add(panel);

        setVisible(true);
    }
}

public class Main {
    public static void main(String[] args) {
        new MyFrame();
    }
}
