Hello there I know there are other threads like this many with solutions that I have tried but to no avail. The main thing is I keep getting a NullPointerException each time! I am not sure where I am going wrong, here is what I have in my method:

 public Image getIcon() {

    URL iconURL = getClass().getResource("src/images/convert.png");
    // iconURL is null when not found
    ImageIcon icon = new ImageIcon(iconURL);

    return icon.getImage();
}

then I am calling this method after i have created my JFrame,

        frame.setIconImage(model.getIcon());

but I am still getting this nullpointer.

EDIT: this is the file tree..

Are you testing this in an exported JAR file or on an IDE? – mid Aug 23 '17 at 12:40
@Midnightas no i have not exported it as a JAR yet....is that why i am going wrong? – Maiwand Aug 23 '17 at 12:44
I'm just making sure, because `getResource` doesn't usually work in exported JARs. – mid Aug 23 '17 at 12:46
Can you screenshot the file tree? (Where convert.png is) – mid Aug 23 '17 at 13:01
@Midnightas see it must be src/images/convert.png, but its giving a nullpointer :( – Maiwand Aug 23 '17 at 13:40
