1、绘制一个红色的心形程序清单：import java.awt.*;import java.awt.geom.*;public class redHeart extends Frame public Color currentColor=Color.red;public intx=114,205,208,294,;public inty=182,117,260,182;public inta=205,294,208,114;public intb=117,181,260,182;public void paint(Graphics g)Arc2D arc;Graphics2D g2d=(Graph
2、ics2D)g;GeneralPath path=new GeneralPath();arc=new Arc2D.Float(100,100,120,100,40,180,Arc2D.OPEN);g2d.setColor(currentColor);g2d.fill(arc);g2d.setColor(currentColor);arc=new Arc2D.Float(190,100,120,100,320,180,Arc2D.OPEN);g2d.fill(arc);g2d.setColor(currentColor);path.moveTo(208, 260);path.lineTo(114, 182);path.moveTo(208, 260);path.lineTo(294,182);g2d.draw(path);g2d.fillPolygon(x, y, 4);g2d.fillPolygon(a, b, 4);public static void main(String args)(new redHeart().setVisible(true);public redHeart()super(“redHeart“);setSize(400,400);结果：
