Q 2) Define abstract class shape with abstract method area ().

Write a java
program to calculate area of circle

abstract class Shape {


abstract double area();
}

class Circle extends Shape {


private double radius;

Circle(double radius) {
this.radius = radius;
}

@Override
double area() {
return Math.PI * radius * radius;
}

public static void main(String[] args) {


Circle circle = new Circle(5); // Example value for radius
System.out.println("Area of the circle: " + circle.area());
}
}

OR

import java.util.Scanner;

public class CalculateCircleArea {


public static void main(String[] args) {
// Create a Scanner for user input
Scanner scanner = new Scanner(System.in);

// Prompt the user to enter the radius


System.out.print("Enter the radius of the circle: ");
double radius = scanner.nextDouble();

// Calculate the area of the circle


double area = Math.PI * Math.pow(radius, 2);

// Display the calculated area


System.out.printf("The area of the circle is: %.2f square units%n", area);

// Close the scanner


scanner.close();
}
}
