Java Program For Finding Volume Using constructing box with 3 params

class Box
{
 double width;
 double height;
 double depth;
        
       

        Box(double w, double h)
 {
          System.out.println("constructing box with 2 params"); 
         width=w;
         height=h;
         depth=10;
        }

      Box(double w, double h, double d)
 {
          System.out.println("constructing box with 3 params"); 
         width=w;
         height=h;
         depth=d;
        }

 

 double volume()
 {
         return width*height*depth;
 
 }
        
}
