//获取屏幕大小
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");//设置窗口标题
this.setBackground(Color.BLACK);
this.setLocation((WINDOW_WIDTH-WIDTH)/2,(WINDOW_HEIGHT-HEIGHT)/2);//设置窗口位置
this.setSize(WIDTH, HEIGHT);//设置窗口大小
this.setLayout(getLayout());//设置窗口布局
this.setVisible(true);//设置窗口可见
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);//设置窗口默认关闭方式
}
public void paint(Graphics g){
double x,y,r;//横纵坐标以及半径
Image image = this.createImage(WIDTH, HEIGHT);
Graphics pic = image.getGraphics();
for (int i = -2; i < 90; i++) {
for (int j = -2; j < 90; j++) {

pic.setColor(Color.MAGENTA);
pic.fillOval((int)x, (int)y, 2, 2);
}
g.drawImage(image,0,0,this);//生成图片
}
}
public static void main(String[] args) {
new Cardioid();
}
}
