Insert an image into Java program

[Roger Fed]

I know that when i want to create an image icon i can write this for example

ImageIcon arrow = new ImageIcon("Path of the image here");

but if i want to run this program in another computer the image will not appear as the path is incorrect
so, I want to save this image in my program so as to run and appear in any computer regardless the path name of the image.
How can i accomplish this?
thanks in advance.........

Check out how resources work, then use getClass().getResource(). This returns a URL that you can pass directly to the ImageIcon constructor.
