    Exclamation SWING:- GUI And Image Problems.

    So I'm using NetBeans 8.0 IDE, and I've compiled my main class (YuGiOh Game I'm working on):-

                break;
            }
        }
    }

    But when I run the jar, it doesn't show the images on the JFrame, I removed
    frame.add(new Main());
    from my main class; as it caused errors, I wonder if this is affecting it?

    Also I'm getting occasional following Array IndexOutofBounds Exceptions (At different instances):

    Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 8, Size: 8
    	at java.util.ArrayList.rangeCheck(ArrayList.java:604)
    	at java.util.ArrayList.get(ArrayList.java:382)
    Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 9, Size: 9
    	at java.util.ArrayList.rangeCheck(ArrayList.java:604)
    	at java.util.ArrayList.get(ArrayList.java:382)
    	at com.github.bewd.yugioh.main.Main.main(Main.java:105)
    Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 8, Size: 8
    	at java.util.ArrayList.rangeCheck(ArrayList.java:604)
    	at java.util.ArrayList.get(ArrayList.java:382)
    	at com.github.bewd.yugioh.main.Main.main(Main.java:110)

    Thanks in advance.

    UPDATE: When I removed the
    frame.add(new Main());
    I noticed that the image does now not show in NetBeans anymore either; but when I add this code back in, it works fine in NetBeans but when I try to run it from a "java -jar" command from a batch file it does not work; Also I've set the Batch File to collect info what's happening in a text file, here's what it says:

    Exception in thread "main" java.lang.IllegalArgumentException: input == null!
    	at javax.imageio.ImageIO.read(Unknown Source)
    	at com.github.bewd.yugioh.main.Main.<init>(Main.java:37)
    	at com.github.bewd.yugioh.main.Main.main(Main.java:62)

    All the Image links are fine, I believe, and are relative to the Jar, not my system.

    You leave out many details that would be helpful:

    Are the images shown when you run from NetBeans?

    How did you build the .jar file?

    Copy and post EXACTLY and in their ENTIRETY the error messages you want help with.

    When I compiled the program, this is what I saw first as error message:-

    Cannot find symbol - variable Card;

    - in this code:

     g.drawImage(sdk1, 0, 0, Card.cardwidth / 5, Card.cardheight / 5, null);

    Check your program again. Maybe you forgot to declare it.

    No, my Card Class has the int: cardwidth set, and the int: cardheight set also.

    Try adding this at the end of your rendering code? Or at the end of the class file...

    JFrame.validate()
    //or
    frame.validate()

    I dont know if this will help, but I used to get the components in the JFrame not show up due to this.

    Also you're getting the arrayoutofbounds exception due to having the for loops going outside the bounds.

    for(int i = 0; i<monsterfield1.size(); i++){
        System.out.println(monsterfield1.get(i).toString() + " has been summoned");
    }

    Try to change things like these to

    for(int i = 0; i < monsterfield1.size() - 1; i++)
    {
        System.out.println(monsterfield1.get(i).toString() + " has been summoned");
    }

    Notice how I minus one from the size of the array. This is due to the method returning the exact amount of items in the list +1 due to it not including the position 0.

    I am quite bad at explaining things but that might clear it up for you. Hope it helps..

    Perhaps what you want is to call repaint() instead of validate. But I did not see the entire code so it is very hard for me to make anything but a guess..

    If the OP is using a regular data structure then this is wrong.
    For any regular array or list the code of the OP should work just fine without any exceptions. If you have 10 elements then you have to iterate over the elements from 0, 1, 2, ..., 9. That is, all indices below 10.

    Yes, yes you are right. .-. I thought he used something else.. ignore that

    If you're interested in trying to fix this, well here's the zip file: Zippyshare.com

    Thanks if you do fix this, I am quite confused by this; it seems to escape my logic.

    Nobody is going to download a shady zip file onto their computer and just do your work for you. Try asking a specific technical question and posting an MCVE, and we'll go from there.
