Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
class AreaOfRectangle 
{
   public static void main(String args[]) 
    {   
       
      Scanner s= new Scanner(System.in);
        
        System.out.println("Enter the length:");
        double l= s.nextDouble();
        System.out.println("Enter the breadth:");
        double b= s.nextDouble();                       
          
        double  area=l*b;
      System.out.println("Area of Rectangle is: " + area);      
   }
}

Result
