如何用Java制作爱心给表白

Java可以作图，不要以为Java功能少

Java的强大功能以致于难以学会

但是可以专门学一处

下面这个是爱心表白作图

送给你喜欢的女孩子吧

import java.awt.Color; import java.awt.Graphics; import java.awt.Image; import java.awt.Toolkit; import javax.swing.JFrame; public class Cardioid extends JFrame{ private static final int WIDTH=500; private static final int HEIGHT=500; private static int WINDOW_WIDTH=Toolkit.getDefaultToolkit().getScreenSize().width; private static int WINDOW_HEIGHT=Toolkit.getDefaultToolkit().getScreenSize().height; public Cardioid(){ super("I love you"); this.setBackground(Color.BLACK); this.setLocation((WINDOW_WIDTH-WIDTH)/2,(WINDOW_HEIGHT-HEIGHT)/2); this.setSize(WIDTH, HEIGHT); this.setLayout(getLayout()); this.setVisible(true); this.setDefaultCloseOperation(DISPOSE_ON_CLOSE); } public void paint(Graphics g){ double x,y,r; Image image=this.createImage(WIDTH,HEIGHT); Graphics pic=image.getGraphics(); for(int i=-2;i<90;i++){ for(int j=-2;j<90;j++){ r=Math.PI/45+Math.PI/45*i*(1-Math.sin(Math.PI/45*j))*18; x=r*Math.cos(Math.PI/45*j)*Math.sin(Math.PI/45*i)+WIDTH/2; y=-r*Math.sin(Math.PI/45*j)+HEIGHT/3; pic.setColor(Color.MAGENTA); pic.fillOval((int)x, (int)y, 2, 2); } g.drawImage(image, 0, 0, this); } } public static void main(String[] args) { new Cardioid(); } }
