设置图标图像JFrame

Question

I have a .ico file I want to use as the title icon for my program. I'm pretty sure I have to use the setIconImage(image) method but every way I've tried doing this has ended in failure.

I've tried quite a few different methods but none have worked for me. One I thought would have worked was the following:

    Image image = new ImageIcon(this.getClass().getResource("Icon.ico").getImage());
    setIconImage(image);

Only problem with this however is the type mismatch. Both the main class and the icon are in the same package but I can't seem to set it no matter how hard I try.

What would be the correct method for doing this?

Answer 1

The best way is probably to use ImageIO to read the Image from the jar.

Image image = ImageIO.read(this.getClass().getResource("/me/spedwards/program/Icon.ico"));
setIconImage(image);

Answer 2

This works for me

setIconImage(new ImageIcon("Icon.ico").getImage());
