Program To Print Amicable Pair Number JAVA
Write a Program to print whether the inputted numbers is Amicable Pair or not.
The amicable numbers are two different numbers (a pair of numbers) so related that the sum of the factors (excluding the number itself) of one of the number is equal to the other.
Example : 220 & 284
The divisor of 220 are: 1,2,4,5,10,11,20,22,44,55,and 110 , The sum of divisor of 220 is = 284
The divisor of 284 are: 1,2,4,71,142, The sum of divisor of 284 is = 220

}
}
for(int i = 1;i < b;i++)
{

{
sum_b = sum_b + i;
}
}
if(sum_a==b && sum_b==a)
{
System.out.println("It is amicable pair");
}
else
{
System.out.println("It is not amicable pair");
}
}
