我正在和我的朋友一起做一个跳棋游戏，我负责棋子、棋盘等。我通过另一个也在玩跳棋游戏并让它工作的朋友得到了使用 iconImages 的想法。由于某种原因，检查器图像未显示。任何想法将不胜感激。

public class checkerboard {

    public static void main(String[] args) {

用于导入图像使用 BufferedImage

BufferedImage buttonIcon = ImageIO.read(new File("buttonIconPath"));

并用于创建按钮

button = new JButton(new ImageIcon(buttonIcon));

之后用于button.setContentAreaFilled(false);显示图像，仅此而已

您需要检查您的应用程序期望您的图像驻留的位置。添加

System.out.println(System.getProperty("user.dir"));

并将您的图像复制到该位置。
