Vote count: -1

Trying to write Space Invaders game.

You can see my code for this app on GitHub.

I using this tutorial and complete first 14 lessons and all was OK, program compiled without errors and run correctly. But after video 15 program stop working correctly and shows following errors in console:

Exception in thread "Thread-3" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

at spaceinvaders.display.Display.run(Display.java:86)

Please, help me find reason of this error and fix this.
