That is, a stack is like a stack of plates on a table. The first plate put down on the table is the last plate to be used. Stacks are controlled through two operations traditionally called push and pop. Use the Class name for this program as Stack, Stack() as constructor, push() and pop() as method.

package volbox;
class Bigbox
{
   double width;

   double height;
}
public class Volbox
{
  public static void main(String[] args)
  {
    Bigbox lbox=new Bigbox();
    lbox.width=15;
    lbox.depth=8;
    lbox.height=20;
    double vol=lbox.width * lbox.depth * lbox.height;
    System.out.println("Volume of box is:" +vol);
  }
}
