Write a Java program to create an abstract class named Shape that contains two integers and an  empty method named print Area (). Provide three classes named Rectangle, Triangle, and Circle  such that each one of the classes extends the class Shape. Each one of the classes contains only  the method print Area () that prints the area of the given shape.

import java.util.*;

abstract class Shape {
	int length, breadth, radius;

	Scanner input = new Scanner(System.in);

	abstract void printArea();

}

class Rectangle extends Shape {
	void printArea() 

{
		

System.out.println("*** Finding the Area of Rectangle ***");
System.out.print("Enter length and breadth: ");
length = input.nextInt();
breadth = input.nextInt();
System.out.println("The area of Rectangle is: " + length * breadth);
	}
}

class Triangle extends Shape 

{
	void printArea()

 {
       System.out.println("\n*** Finding the Area of Triangle ***");
    System.out.print("Enter Base And Height: ");
    length = input.nextInt();
    breadth = input.nextInt();
 

System.out.println("The area of Rectangle is: " + (length * breadth) / 2);

  }
}

class Cricle extends Shape

 {
    void printArea() 

    {
	System.out.println("\n*** Finding the Area of Cricle ***");
	System.out.print("Enter Radius: ");
	radius = input.nextInt();

System.out.println("The area of Rectangle is: " + 3.14f * radius * radius);
    }
}

public class AbstractClassExample

 {

public static void main(String[] args)

 {
   Rectangle rec = new Rectangle();
   rec.printArea();

   Triangle tri = new Triangle();
   tri.printArea();
 		
   Cricle cri = new Cricle();
    cri.printArea();
}
}
