 # Input a number and check if it is an automorphic number or not using a function in Java

###### Function - Question 10

In this question, we will see how to input a number and check if it is an automorphic number or not in Java programming using a function. To know more about function click on the function lesson.

Q10) Write a program in Java to input a number and check if it is an automorphic number or not using a function.

A number N is said to be automorphic, if its square ends in N for example 5 is automorphic, because 52=25, which ends in 5, 25 is automorphic, because 252=625, which ends in 25.

#### Program

``````import java.util.Scanner;

public class Q10
{
public static int automorphic(int num)
{
int x,t,s;
x=1;
t=num;
while(t>0)
{
x=x*10;
t=t/10;
}

s=num*num;   // square of the number
if(s%x==num)
{
return 1;
}
return 0;
}

public static void main(String args[])
{
int n;
Scanner sc=new Scanner(System.in);
System.out.println("Enter a numbers ");
n=sc.nextInt();

if(automorphic(n)==1)
{
System.out.print("Automorphic Number");
}
else
{
System.out.print("Not Automorphic Number");
}
}
}``````

#### Output

```Enter a number 25
Automorphic Number```
