When I have a random number generated, how do I get a class to appear in a location related to the number generated??
For instance a bingo grid, I generate a number 5, how do I make my counter subclass place in the correct location on the grid??

Placing Objects
You will have three sets of information:
(1) the top-left location coordinates for where counter zero will go (counting in java starts at zero)
(2) the number of rows across and columns down that make up the total area where the counters are placed
(3) the horizontal gap between each counter location across and vertical gap between each counter down
Giving these data fields names: (1) topLeftX and topLeftY (2) rows and cols (3) hGap and vGap. Since, rows times columns is the total number of possible counters, each location can be arrived at by
int rand = Greenfoot.getRandomNumber(rows*cols); int x = topLeftX+hGap*(rand%cols); int y = topLeftY+vGap*(rand/cols);
