}// end class Box
9.Add a Constructor to Class Box for a cube,which as 1 parameter,side
Solution
 public class Box
 {
 double length;
 double width;
 double height;
   
 Box(double l, double w, double h)
 {
 length = l;
 width = w;
 height = h;
 }// Box( )
   
//Defines cube with all dimensions equal to parameter side.
 Box(double side)
 {
 length = width = height = side;
 }
   
 double volume( )
 {
 return length * width * height;
 }// end volume( )
 }// end class Box
