用IEDA写一个动态爱心

好的，以下是用Java Swing编写的动态爱心代码：

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Point;
import java.util.ArrayList;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class DynamicHeart extends JPanel implements Runnable {
    private static final long serialVersionUID = 1L;
    private ArrayList<Point> hearts = new ArrayList<Point>();
    private final int HEART_SIZE = 50; // 爱心大小
    private final int HEART_X = 150; // 爱心初始位置
    private final int HEART_Y = 150;
    private final int HEART_SPEED = 5; // 爱心移动速度
    private int dx = HEART_SPEED; // x轴移动距离
    private int dy = HEART_SPEED; // y轴移动距离

    public DynamicHeart() {
        JFrame frame = new JFrame("动态爱心");
        frame.setSize(400, 400);
        frame.setLocationRelativeTo(null);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(this);
        frame.setVisible(true);
        hearts.add(new Point(HEART_X, HEART_Y));
        new Thread(this).start();
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        g.setColor(Color.RED);
        for (Point p : hearts) {
            g.fillOval(p.x, p.y, HEART_SIZE, HEART_SIZE);
        }
    }

    @Override
    public void run() {
        while (true) {
            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            for (Point p : hearts) {
                p.x += dx;
                p.y += dy;
                if (p.x <= 0 || p.x >= getWidth() - HEART_SIZE) {
                    dx = -dx;
                }
                if (p.y <= 0 || p.y >= getHeight() - HEART_SIZE) {
                    dy = -dy;
                }
            }
            repaint();
        }
    }

    public static void main(String[] args) {
        new DynamicHeart();
    }
}

运行以上代码，即可看到一个动态爱心的窗口。当然，你可以根据自己的需求对代码进行修改。
