# Java: Check two numbers are Amicable numbers or not

## Java Numbers: Exercise-16 with Solution

Write a Java program to check two numbers are Amicable numbers or not.

Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number.

The first ten amicable pairs are: (220, 284), (1184, 1210), (2620, 2924), (5020, 5564), (6232, 6368), (10744, 10856), (12285, 14595), (17296, 18416), (63020, 76084), and (66928, 66992).

*Test Data*

Input the first number: 220

Input the second number: 284

**Pictorial Presentation:**

**Sample Solution:**

**Java Code:**

```
import java.util.Scanner;
public class Example16
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Input the first number: ");
int num1 = in.nextInt();
System.out.print("Input the second number: ");
int num2 = in.nextInt();
int sum_num1 = 0, sum_num2 = 0;
for (int i = 1; i <= num1; i++) {
if (num1 % i == 0)
sum_num1 += i;
}
for (int i = 1; i <= num2; i++) {
if (num2 % i == 0)
sum_num2 += i;
}
if (sum_num1 == sum_num2)
System.out.println("These numbers are amicable.");
else
System.out.println("These numbers are not amicable.");
System.out.println("\n");
}
}
```

Sample Output:

Input the first number: 220 Input the second number: 284 These numbers are amicable.
