Java program amicable numbers

Output:

Enter two numbers to check they are amicable or not:
220
284
220 and 284 are amicable numbers

Implementation:

/* Amicable numbers are the numbers which has their sum of divisors equal to one another 
   For example:
              consider the numbers a=220 and b=284
              
              the divisors of 220 are:
              1 2 4 5 10 11 20 22 44 55 110
              
              the divisors of 284 are:
              1 2 4 71 142
              
              Now, adding the divisors of 220
              1+2+4+5+10+11+20+22+44+55+110 = 284 , which is equal to number b=284
              
              Now, adding the divisors of 284
              1+2+4+71+142 = 220, which is equal to number a=220
              
              Hence, the numbers 220 and 284 are amicable numbers
