推荐答案

setIconImage(new ImageIcon("images/die.bmp").getImage()); 

ImageIcon image = new ImageIcon( "/images/Board.jpg" ); 

您使用了2种不同的方法来具体化图像的位置.我想第一个是正确的.您的边框图标改变了吗?

You used 2 different ways to spcify the location of the image. I would guess the first is correct. Did your frame icon change?

此外，如何使用图标教程可以提供更好的效果图片作为资源的示例.

Also, the How to Use Icons tutorial gives better examples by the the image as a resource.
