    On line `19` of your `Logo_Screen` class, a `NullPointerException` is being thrown. Fix this problem by making whatever is `null` _not_ `null`, or by otherwise properly handling the `null` reference. – Slaw Jun 02 '22 at 19:52
  • By the way, `catch (Exception e) { e.printStackTrace(); }` is an astoundingly bad thing to do. In this case you're pretty much only ever going to get an InterruptedException, but swallowing exceptions like that is going to burn you one day. – David Conrad Jun 02 '22 at 19:57
  • He! Bro I don't Understand This. Can you tell me how to fix it? – Supun Madushanka Jun 03 '22 at 03:35
