Write a program to accept two numbers n1 and n2 in the main method. With the help of a function void amicable(int,int) display the message"amicable" if they are amicable otherwise display the message "not amicable" if they are not amicable. [Amicable numbers are two nos if each is equal to the sum of the proper divisors of the other nos .]Example -- 220 and 284 are amicable numbers.​

java.io.*; class GFG { STATIC int divSum(int n) { int result = 0; for (int i = 2; i <= Math.sqrt(n); i++) { if (n % i == 0) { if (i == (n / i)) result += i; else result += (i + n / i); } } return (result + 1); } static boolean areAmicable(int x, int y) { if (divSum(x) != y) return FALSE; return (divSum(y) == x); } public static void MAIN (String[] args) { int x = 220, y = 284; if (areAmicable(x, y)) System.out.println( "Yes"); else System.out.println("No"); } }
