My advanced Hello World program is a version of the old game Snake.

• normal playing experience of Snake but hardware-accelerated
• 5 different fruits that can be eaten to enlarge the Snake
• theoretically Start- and Endscreen, currently mostly unused
• theoretically visual display whether a result is good or bad, commented out for now as it does not appear to work as expected

• Snake:
  • stores the body parts, their position and the general direction of the Snake
  • checks, whether the Snake touches itself, the outer bounds or food
• Main:
  • the class where public static void main(String[] args){} is located
  • stores the GameWindow used
• GameWindow:
  • displays all visual components used in the game
  • stores the Snake object
• FoodFactory:
  • generates new Food
• other classes in the ui-package:
  • as the name suggests, defines the visual appearance before and after games
