Java program to input two integers and check whether it forms an amicable pair or not

Write a program to input two integers and check whether it forms an amicable pair or not. An amicable pair is such that, the sum of the factors excluding itself of one number is the other number and sum of the factors excluding itself of the other number is this number.

Example, (220, 284) . Since sum of factors excluding itself of:

220= 1+2+4+5+10+11+20+22+ 44+55+110=284

284= 1+ 2+4+71+142=220.

import java.util.*;
class Amicable
{
	public static void main(Strign arr[])
	{
		Scanner sc=new Scanner(System.in);
		int i,a,b,sa=0,sb=0;
		System.out.println("Enter 2 integers:");
		a=sc.nextInt();
		b=sc.nextInt();
		for(i=1;i<a;i++)
		{
			if(a%i==0)
				sa+=i;
		}
		for(i=1;i<b;i++)
		{
			if(b%i==0)
				sb+=i;
		}
		if(sa==b && sb==a)
			System.out.println("Amicable pair");
		else
			System.out.println("Not Amicable pair");
	}
