Create a class SimpleCalculator that has functionality of addition, substraction division, multiplication, square and squareroot.

class Calculator

  {

   public void calc()

    {

    int add, sub, mul, a, b, n,sqr,m;

    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);

    n=Integer.parseInt(System.console().readLine("enter the no. jiska square niklna hai  :"));

    sqr=n*n;

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

    m=Integer.parseInt(System.console().readLine("enter the no. jiska square niklna hai  :"));

    double sqtroot=Math.sqrt(m);

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

   }

 

public static void main(String args[])

    {

      Calculator s=new Calculator();

      s.calc();

    

      

    }

 }
