该程序应该在用户点击的位置绘制圆圈。目前，它只画了5个圆圈。我想知道，如何修改这段代码，以便它可以无限制地绘制圆圈。考虑一个我不知道应该绘制的圆圈数量的场景。这是我的代码：
公共类DrawingBoard {
public static void main(String[] args){
new LookAndFeel();
}
}
类LookAndFeel扩展了JPanel {
JFrame f;
int n = 0;
double points[][] = new double[6][5];
EventManager EMobj = new EventManager();
public LookAndFeel(){
f = new JFrame("Drawing Board");
f.setBounds(0,0,1920,1080);
f.add(this);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
f.setResizable(false);
addMouseListener(EMobj);
}
public void paintComponent(Graphics g){
g.setColor(Color.RED);
if(n >= 1)
g.fillOval((int)points[0][0], (int)points[1][0], 80, 80);
if(n >= 2)
g.fillOval((int)points[1][1], (int)points[2][1], 80, 80);
if(n >= 3)
g.fillOval((int)points[2][2], (int)points[3][2], 80, 80);
if(n >= 4)
g.fillOval((int)points[3][3], (int)points[4][3], 80, 80);
if(n >= 5)
g.fillOval((int)points[4][4], (int)points[5][4], 80, 80);
if(n==5)
removeMouseListener(EMobj);
}
class EventManager extends MouseAdapter{
public void mouseClicked(MouseEvent e){
points[n][n] = e.getX();
points[n+1][n] = e.getY();
n++;
repaint();
}
}
}
