Java program automorphic number

Output:

Enter the number to check whether automorphic number or not:
76
Automorphic number

Implementation:

/* An automorphic number is a number whose square ends in the same digits
   as the number itself. 
   For example: 5 * 5 = 25
                6 * 6 = 36
                76 * 76 = 5776
                890625 * 890625 = 793212890625
    So, 5, 6, 7, 76 and 890625 are all automorphic numbers
