Harshad Number or Niven Number in Java

Harshad numbers are those integers which are divisible by the sum of the digits of the number. Harshad numbers were defined by a mathematician from India, D. R. Kaprekar. Harshad numbers are also called Niven numbers. For example, the number 198. Sum of the digits of the number, 198 => 1 + 9 + 8 = 18, and, 18 * 11 = 198. Hence, the number 198 is a Harshad number. Below is a program that inputs a number, and checks whether it is

Automorphic Number in Java

Automorphic numbers are those numbers that when squared have the exact same end digits as the number. For example, the number 376. Now the square of the number, 376 is 141376. The last three digits of the square are exactly like the number themselves. Hence, 376 is an Automorphic Number. However, let the number is 45. Now the square of the number, 45 is 2025. The last two digits of the square (25) are not same as the number 45.
