使用java编写动态爱心程序

可以使用Java编写动态爱心程序，下面是一个简单的代码示例：

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

public class LoveHeart extends JPanel {

  public void paint(Graphics g) {
    super.paint(g);
    int x1 = 150, y1 = 150;
    int x2 = 50, y2 = 50;
    g.setColor(Color.RED);
    for (int i = 0; i <= 90; i++) {
      x1 = x1 + 2;
      y1 = (int) (y1 - (Math.sin(Math.toRadians(i)) * 2));
      x2 = x2 + 2;
      y2 = (int) (y2 + (Math.sin(Math.toRadians(i)) * 2));
      g.drawLine(x1, y1, x2, y2);
    }
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setSize(500, 500);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(new LoveHeart());
    frame.setVisible(true);
  }
}

这个代码使用了Java的图形绘制API，绘制了一个动态的爱心。
