Java program to implement constructor overloading by passing different number of parameter of different types.

class Box

{

int length, breadth, height;

Box ()

{

length = breadth = height = 2;

System.out.println ("Intialized with default constructor");

} Box (int l, int b)

{

length = l;

breadth = b;

height = 2;

System.out.

println

("Initialized with parameterized constructor having 2 params");

}

Box (int l, int b, int h)

{

length = l;

breadth = b;

height = h;

System.out.

println ("Initialized with parameterized constructor having 3 params");

} public int getVolume ()

{

return length * breadth * height;

}

public static void main (String args[])

{

Box box1 = new Box ();

System.out.println ("The volume of Box 1 is :" box1.getVolume ());

Box box2 = new Box (10, 20);

System.out.println ("Volume of Box 2 is :" box2.getVolume ());

Box box3 = new Box (10, 20, 30);

System.out.println ("Volume of Box 3 is :" box3.getVolume ());
