        {
            if (i%2 == 0)
            {

                }
                pane.add(panel);
            }
        }
        board.setVisible(true);

我有用java编写的代码，我想知道如何添加两个圆圈以便创建一个有两个部分的板子？感谢。

P.S我是java的新手

覆盖paintComponent（Graphics g）方法。

// create Image 
Image i = new ImageIcon("//filepath").getImage();
int pointXForFirstPiece = 0; // update for the x position of where your piece will be
int pointYForFirstPiece = 0; // update for the y position

public void paintComponent(Graphics g) {
    // do the painting for the two objects here
    // paint image
    // create another image object as done above, and then 
    // rewrite the line below for the second piece
    g.drawImage(i, pointXForFirstPiece, pointYForFirstPiece, null);
}

希望这会有所帮助
