Change the order of color assignment

Listing 2 declares and initializes an array of color data

• that is used in the original version of the SimpleTurtle class
• to assign colors to the turtles on a cyclical basis
• as they are instantiated.

  private static Color[] colorArray = 
    { Color.green, 
      Color.cyan, 
      new Color(204,0,204), 
      Color.gray};
