JAVA PROGRAM TO OVERLOADING CONSTRUCTOR WORK

//program to overloading constructor ----how overloading constructor actually work

PROGRAM CODE-----

class Box

{

double width;

double height;

double depth;

Box()   //constructor when no dimensions specified

{

width=1;

height=1;

depth=1;

}

Box(double x) // constructor used when one dimensions specified like a cube

{

width=height=depth=x;

}

Box(double w , double h, double d ) // constructor used when three dimensions specified

{

width=w;

height=h;

depth=d;

}

Box(Box b) //  pass object to constructor

{

width=b.width;

height=b.height;

depth=b.depth;

}

double volume()  //calculate volume of box

{

return width*height*depth;

}

}

class CallBox

{

public static void main(String ar[])

{

Box mybox1=new Box();    //no parameter

Box mybox2=new Box(4.0);  //one parameter

Box mybox3=new Box(1.2,2.2,5.1);

Box mybox4 = new Box(mybox2);  // pass copy of one parameter  object

double vol;

vol=mybox1.volume();

System.out.println("Volume of first box is"+vol);

  vol=mybox2.volume();

System.out.println("Volume of second box is"+vol);

vol=mybox3.volume();

System.out.println("Volume of third box is"+vol);

vol=mybox4.volume();

System.out.println("Volume of fourth box is"+vol);

}

}
