idea代码块变成绿色了

好的，您需要使用
Java Swing来实现动态画爱心的
代码。以下是参考
代码： “`
java import
java.awt.Color; import
java.awt.Graphics; import
java.awt.Point; import
java.util.ArrayList; import
java.util.List; import
javax.swing.JFrame; import
javax.swing.JPanel; public class DynamicHeartDemo extends JPanel {idea代码块变成绿色了 private static final long serialVersionUID = 1L; private int refresh = 20; private int size = 10; private List<Point> points = new ArrayList<Point>(); public DynamicHeartDemo() { setBackground(Color.white); } @Override public void paint(Graphics g) { super.paint(g); for (Point p : points) { int x = p.x; int y = p.y; g.fillOval(x, y, size, size); } } private void drawHeart() { for (double t = 0; t <= Math.PI; t += 0.01) { int x = (int) (16 * Math.pow(Math.sin(t), 3)); int y = (int) (13 * Math.cos(t) – 5 * Math.cos(2 * t) – 2 * Math.cos(3 * t) – Math.cos(4 * t)); x = x * size + getWidth() / 2; y = -y * size + getHeight() / 2; points.add(new Point(x, y)); } } public void start() { drawHeart(); while (true) { try { Thread.sleep(refresh); } catch (InterruptedException e) { e.printStackTrace(); } List<Point> removePoints = new ArrayList<Point>(); for (Point p : points) { if (p.y <= 0) { removePoints.add(p); continue; } p.x -= 1; p.y -= 1; } points.removeAll(removePoints); repaint(); } } public static void main(String[] args) { JFrame frame = new JFrame(); frame.setSize(800, 600); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); DynamicHeartDemo panel = new DynamicHeartDemo(); frame.add(panel); frame.setVisible(true); panel.start(); } } “` 这段
代码可以在
Java
开发工具
IDEA
中使用。您只需要将以上
代码复制到您的
IDEA项目
中，然后运行即可。希望能够帮到您！今天的文章
