One of the best way to be in shape with our programming is to solve problems. So we present below the problem and sample solution to :

Determine Automorphic number program in java using while loop

So we try to solve if we can determine if a number is Automorphic or not. See below code:

/**
 * An example program that Determine Automorphic number program in java using while loop
 */
public class ExampleProgram {
    public static void main(String[] args) {
        System.out.println(376 + " is automorphic? : " + isaAtomorphic(376));
        System.out.println(25 + " is automorphic? : " + isaAtomorphic(25));
        System.out.println(123 + " is automorphic? : " + isaAtomorphic(123));
        System.out.println(200 + " is automorphic? : " + isaAtomorphic(200));
    }
    public static boolean isaAtomorphic(int n) {
        int square = n * n;
        while (n > 0) {
            int d1 = n % 10;
            int d2 = square % 10;
            if (d1 != d2) {
                return false;
            }
            n = n / 10;
            square = square / 10;
        }
        return true;
    }
}

And we get results below:

376 is automorphic? : true
25 is automorphic? : true
123 is automorphic? : false
200 is automorphic? : false
