Create icon that consists of one pixel (better transparent) and use it. If you need such icon contact me. I will send you.
创建由一个像素（更好的透明）组成的图标并使用它。如果您需要这样的图标，请联系我。我会送你。

It's always good to keep a copy of the Java source codearound. The code for java.awt.Window (a superclass of JFrame) has the following code for setIconImage:
保留一份Java 源代码的副本总是好的。java.awt.Window（JFrame 的超类）的代码具有以下代码setIconImage：
public void setIconImage(Image image)
{
ArrayList<Image> imageList = new ArrayList<Image>();
if (image != null)
{
imageList.add(image);
}
setIconImages(imageList);
}
You can see that passing in a null image is the same as doing nothing so you'll have to pass in an image to get rid of the coffee cup. As others have suggested using a 1 x 1 transparent icon is your best bet. Here is some code to create the icon:
你可以看到传入一个空图像与什么都不做是一样的，所以你必须传入一个图像才能摆脱咖啡杯。正如其他人所建议的那样，使用 1 x 1 透明图标是您最好的选择。下面是一些创建图标的代码：
Image icon = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB_PRE);
myFrame.setIconImage(icon);

You can set the image icon to a transparent image which will remove the coffee cup. I don't believe it is possible to get rid of the default icon otherwise.
您可以将图像图标设置为透明图像，这将移除咖啡杯。我不相信有可能以其他方式摆脱默认图标。

You could just use gimp or photoshop or even paint and create a 1x1px, transparent image, export it (.png or .jpg, doesnt matter?). Then apply it:
您可以只使用 gimp 或 photoshop 甚至绘画并创建一个 1x1px 的透明图像，然后将其导出（.png 或 .jpg，无所谓？）。然后应用它：
ImageIcon frameIcon = new ImageIcon("files\yourfile.png");
frame.setIconImage(frameIcon.getImage());
Should be fine.
应该没事。
