### Java Find Automorphic numbers

In this section, you will learn how to find the automorphic numbers between 1 and 1000.

Automorphic numbers are the numbers whose square ends with the number itself or you can say it is a number whose square ends with the given integer. For example,5 is an automorphic number as the square of 5 is 25 and its square consists of number 5 in the end. Similarly 6 is an automorphic number as the square of 6 is 36 and its square consists of number 6 at the end. Here we are going to find the automorphic numbers between 1 and 1000.

Here is the code:

```class FindAutomorphicNumber {
public static void main(String args[]) {
long num, n, sq, n1, n2;
System.out.println("Automorphic Numbers between 1 and 1000 are: ");
for (long i = 1; i < 1000; i++) {
n = i;
sq = n * n;
while (n > 0) {
n1 = n % 10;
n2 = sq % 10;
if (n1 != n2)
break;
n = n / 10;
sq = sq / 10;
}
if (n == 0) {
System.out.println(i);
}
}
}
}
```

Output:

 1 5 6 25 76 376 625
