Automorphic Number Program in Java2 min read

In this tutorial, you will learn about the Automorphic Number along with an example and also code java to check whether the number is automorphic or not.

What is an Automorphic number?

A number is said to be an automorphic number if the square of the given number ends with the same digits as the number itself. Example: 25, 76, 376, etc.

Automorphic Number

Check Whether a number is an Automorphic Number in Java

Output:

Enter the Number:
25
25 is an Automorphic number

//Another execution
Enter the Number:
23
23 is not an Automorphic number


Java Program to Find all Automorphic Numbers in the Interval

Now what if we need to find Automorphic Numbers between the range of a given number, the above example will not work as it is applied only for a single number.

To check all the numbers within some given range of numbers, we will create a separate function that will return a true or false value. In the main function, we will call the created function in a loop so that it can check/call for every number.

The loop will run from the starting number to the range mentioned in the program.

Output:

Enter the lower Range:
1
Enter the Upper Range:
100
Automorphic numbers between 1 and 100
1 5 6 25 76
