Re: Using arrays of objects ?

I would probably use an ArrayList (from java.util). I would also define either an
interface or base class for Tool, from which all of the tools are derived, and
(using Java 5 or higher) parameterize the ArrayList:

ArrayList<Tool> toolbox = new ArrayList<Tool>();

To operate on Tool in the toolbox (again, with Java 5 or higher), you can use:

for (Tool tool : toolbox)
{
//tool variable contains the current tool
}
