Java Code:

    Stack stack = new Stack();

    for (int i = 0; i < 10; i++)
      stack.push(new Integer(i));

    System.out.println("stack = " + stack);

    // Treating a stack as a Vector:
    stack.addElement("The last line");

    System.out.println("element 5 = " + stack.elementAt(5));
    System.out.println("popping elements:");

    while (!stack.empty())
      System.out.println(stack.pop());
