Now let's see what our Stack and StackEnumerator classes can do. (Note that
this is by no means a thorough test!)
package examples;
/**
* Tests the Stack and StackIterator classes
*/
public class StackTest
{
/**
* Main entry point
*/
public static void main(String[] args)
{
Stack aStack = new Stack(10);
for (int i = 0; i < aStack.getMaxStackSize(); i++)
aStack.push(i*i);
StackEnumerator enumerator = new StackEnumerator(aStack);
while (enumerator.hasMoreElements())
{
int value = (Integer) enumerator.nextElement();
System.out.print(" " + value);
}
System.out.println();
}
}

As you can see, the main method creates an instance of Stack, pushes some
values onto the stack, and then uses a StackEnumerator to enumerate all the
values on the stack.
When run, this program outputs the following:
0 1 4 9 16 25 36 49 64 81
