Write a class Automorphic to check whether a number is Automorphic or not using function - JAVA

 Write a class Automorphic  to check whether a number is Automorphic or not using function with the help of a method

Int digit(int n)

Solution

import java.io.*;

/**

 * class Automorphic

*

 */

public class Automorphic

{

    int digits(int n)

    {

        int c,p,k;c=0;k=0;

        while(n!=0)

        {

            k=n/10;

            c=c+1;

            n=k;

        }

        return(c);

    }

    public static void main(String args[])throws IOException

    {

        InputStreamReader read =new InputStreamReader(System.in);

        BufferedReader in =new BufferedReader(read);

        int m,n,p,b;

        double r;

        r = 0;

        Automorphic ob= new Automorphic();

        System.out.println("Enter your no.");

        n=Integer.parseInt(in.readLine());

        m= n;

        p= m * m;

        b=ob.digits(n);

        r=p % (Math.pow(10,b));

        if(m==r)

            System.out.println(m + " is an Automorphic no.");

        else

            System.out.println(m + " is not an Automorphic no.");

    }

}

Output;

Enter your no.

625

625 is an Automorphic no.

Enter your no.

525

525 is not an Automorphic no.
