  5. Re: Having problem checking number of attempts to login

    You'll want to ask this in a Javascript forum not a Java forum. The languages are pretty far apart you know. Google can help you find the correct spot to post this.
  6. Re: Need Help with Rendering the screen (with volatile images)

    You will want to post the actual line of code that is throwing the NPE.
  7. Re: Need Help with Rendering the screen (with volatile images)

    So yeah, you're still not telling us which variable is null.

    The lines may be created by borders, but it's hard to tell as your images are so small.

  14. Re: Stuck, and i need this to be solved within 2 days.

    You give us things we don't need: a due date, you give us some requirements and some code (unformatted), but you don't ask a specific answerable question, one that tells us where you're stuck...

    Re: JDialog not working properly

    Your best bit is to:

    First and foremost, always use the formatting tools of whatever forum you're posting your code on so that the code retains its formatting. Different forums use different...

    What you've done is to post your entire assignment without showing what work you've done, without asking a specific question, and that is not how to get help here (or at any forum). For one, we have...

    Re: Problem with my program! Pls HELP!

    The firstMiddleLast() method is a method of the Name class, and to call it, you must call it on a Name object. You're calling it as if it were a static method of the NameTest class, and it's not. So...

    If it's to be a constant, then make it a final variable. Or if I'm misunderstanding you, please clarify your problem some more.
  23. Re: Synchronized a integer variable in Java
