                 JOptionPane.showMessageDialog(null, "You played and walked away with $" + cash);  
     
                 System.exit(0);  
     
             }  
     
         }   
     
     
     
         public static void main(String[] args) {  
     
             new BlackJack();   
         }  }



    I am using Bufferedimage however an image only displays a card(ex. 4clubs). When i try to call all the images by writing the filename(Cards) none of the images appear in the game. Any help would be appreciated!!

    Does this code compile without errors? I get 15 errors.
    What version of the JDK are you using?

    This makes no sense to me:
    what is an image supposed to display if not a card?
    how can you 'call' an image?
    what does 'writing the filename(Cards)' mean?
