Program to check whether two numbers are Amicable Numbers

/**
 * class amicablenum checks whether a number is Amicable Number or not.
 * "Amicable numbers are a pair of numbers with the following property: the sum of all of the proper divisors of the first number (not including itself) 
 * exactly equals the second number while the sum of all of the proper divisors of the second number (not including itself) likewise equals the first number."
 * Ex: 220,284. proper divisors of 220:
 *1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110(sum=284)
 *proper divisors of 284:
 *1, 2, 4, 71, 142(sum=220)

Output:

Enter 2 numbers to be checked for Amicable numbers
220
284
Proper divisors of 220 are:
 1 2 4 5 10 11 20 22 44 55 110
Proper divisors of 284 are:
 1 2 4 71 142
Numbers are Amicable numbers
