I was trying to make splashes for my small game menu. In the IDE (I use Netbeans) everthing works fine, but if I compile and run the jar file it gives the following exception:

    Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Here's the code:

    public MenuDrawing(JFrame f) {
    addMouseListener(this);
    Frame = f;
    qualityHints = new RenderingHints(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
    qualityHints.put(
            RenderingHints.KEY_RENDERING,
            RenderingHints.VALUE_RENDER_QUALITY);
    String[] Splashes = getSplashes("/resources/splashes.txt");
    SelectedSplash = getRandomSplash(Splashes);
}

private String getRandomSplash(String[] s) {
    String Random = s[new Random().nextInt(s.length)];
    System.out.println(Random);
    return Random;
}

private String[] getSplashes(String Name) {
    String[] sp = null;
    try {
        String content = new Scanner(new File(getClass().getResource(Name).getFile())).useDelimiter("\\Z").next();
        sp = content.split("³");
    } catch (IOException ex) {
    }
    return sp;
}

I hope you can help me! :)

PS: Heres the Complete class if this helps!
