help with arrays

Arrays are mainly used for the arrangement of things (like a chessboard, or grid-layout) and for listing things (anything from ints to objects). For some examples: a series of scores for the different levels in a game; the layout of the levels; a list of objects, colors, or values to be randomly chosen from or for each item to be used for a specific purpose (such as the x and y coordinates of a polygon; where an array of x values and an array of y values are used as argument in the 'drawPolygon(int, int, int)' and 'fillPolygon(int, int, int)' methods of the GreenfootImage class.

Arrays works like the List class (but is simpler and doesn't have any methods). Arrays are used if you need a collection of objects. An example of this would be making an animation for one of your actors. You would then create a new array like this I think (please correct me if I'm wrong): GreenfootImage images = new GreenfootImage; This creates an array containing 5 GreenfootImage objects. Now a setup of the array would look like this for instance: images = new GreenfootImage("image1"); images = new GreenfootImage("image2"); And so on (this is not a recommended setup for large arrays). Now to run the animation you want a counter and the code would look something like this: private int counter = 0; Hope this makes sense. And as always danpost has faster response.. :)
