Overloading Constructor:

Overloading Constructor:

package overloadingconstrucror;

public class Box {
    double width;
    double height;
    double depth;
   
    Box(double w,double h,double d){
    width=w;
    height=h;
    depth=d;
    }
   
    Box(){
    width=-2;
    height=-2;
    depth=-2;
    }
   
    //construcror used when cube is created
    Box(double leng){
    width=height=depth=leng;
    }
    double volume(){
    return width*height*depth;
    }
}

public class OverloadConstructor {

    public static void main(String[] args) {

        Box obj = new Box(5,10,15);

        Box obj1= new Box();

        Box obj2 = new Box(6);

        

        double vol;

        

        vol=obj.volume();

        System.out.println("volume "+vol);

        

        vol=obj2.volume();

        System.out.println("Volume "+vol);

    }

}

The above code give the output as:

run:

volume 750.0

Volume 216.0
