2D game ImageIO import issue

Question

I am making a 2d game based on minecraft. The code below worked on my pc but not my mac. The image I am trying to load is in the Background folder inside the Resources folder. Other posts I have read suggest the error is because my image couldn't be found but I don't know what else to put for the image location.

here is my code:

public MenuState(GameStateManager gsm) {

    super(gsm);

    try {

        // load minecraft Background
        minecraft = ImageIO.read(
            getClass().getResourceAsStream("/Backgrounds/minecraft.png ")
                ).getSubimage(0, 300, 400, 300);

        // load floating head
        head = ImageIO.read(
            getClass().getResourceAsStream("/HUD/Hud.gif")
        ).getSubimage(0, 12, 12, 11);

Error Message:

java.lang.IllegalArgumentException: input == null!

Thanks for the help!

It is not a problem of ImageIO. It is a problem of finding the resource. Isolate `getResourceAsStream()` and edit it until it returns something != null — Arnaud Denoyelle, Feb 11 '15 at 16:47
Is there a way to find out the images location? I've been trying different locations all day and it always comes out null — Evan Kellough, Feb 11 '15 at 17:03
Your image must be in the classpath. If you are using maven, then place it in src/main/resources. — Arnaud Denoyelle, Feb 11 '15 at 17:32
