Question

我正在努力解决这个问题，有人可以帮我解决这个问题。提前致谢

  public void gui_OCM()
  {  
    Display d = new Display();
    Shell s = new Shell(d, SWT.CLOSE);

    s.setSize(550, 390);
    s.setText("My Application");
    s.setBackground(s.getDisplay().getSystemColor(10));

    InputStream is= getClass().getClassLoader().getResourceAsStream("resource/Hello.PNG")
    Image my_image= new Image(d,is);

它总是显示以下错误：

Exception in thread "main" java.lang.IllegalArgumentException: Argument cannot be null

P.S：资源是我放置图像的文件夹任何建议都会非常感激。感谢
