Week 3 : Programming Assignment 3

Due on 2023-08-17, 23:59 IST

A class Shape is defined with two overloading constructors in it. Another class Test1 is partially defined which inherits the class Shape. The class Test1 should include two overloading constructors as appropriate for some object instantiation shown in main() method. You should define the constructors using the super class constructors. Also, override the method calculate( ) in Test1 to calculate the volume of a Shape.

File name for this program :

import java.util.Scanner;
class Shape{
double length, breadth;
Shape(double l, double b){ //Constructor to initialize a Shape object  
length = l;

double calculate(){// To calculate the area of a shape object
return length * breadth ;

public class Test1 extends Shape{

//Create a derived class constructor which can call the one parametrized constructor of the base class
//Create a derived class constructor which can call the two parametrized constructor of the base class
