Create a class Calculator that has the following features: addition, subtraction, multiplication, division. Create another class named ScientificCalculator that will have the features of Calculator and some other features like: to find square, cube, power, factorial.... Note:Inheritance to complete this task.

class Calculator

  {

   public void calc()

    {

    int add, sub, mul, a, b;

    double div;

    a=Integer.parseInt(System.console().readLine("enter the first no.  :"));

    b=Integer.parseInt(System.console().readLine("enter the second no. :"));

    add=a+b;

    System.out.println("addition of two no.      ="+add);

    sub=a-b;

    System.out.println("substraction of two no.  ="+sub);

    mul=a*b;

    System.out.println("multiplecation of two no.="+mul);

    div=(double)a/b;

    System.out.println("division of two no.      ="+div);

   }

  }

class ScientificCalculator extends Calculator

{

   void scincalc()

   {

    System.out.println("****************values of ScientificCalculator******************");

   int n=Integer.parseInt(System.console().readLine("enter the  no.  :"));

   int sqr=n*n;

   System.out.println("Square  of the no.      ="+sqr);

   int cube=n*n*n;

   System.out.println("cube of the no.="+cube);

   int fact=1;

   for(int j=1;j<=n;j++)

      {

        fact=fact*j;

      }

    System.out.println("factorial of the no.="+fact);

   int d=Integer.parseInt(System.console().readLine("enter the power no.  :"));

   int pow=n;

   for(int i=1;i<d;i++)

     {

     

       pow=pow*n;

     }

  

    System.out.println("power of n to d is ="+pow);

   

  

  }

   public static void main(String args[])

    {

      ScientificCalculator ab=new ScientificCalculator();

      ab.calc();

      ab.scincalc();

      

    }

 }
