Java program to input three integers and find the difference between their sum and their average

Write a java program to input three integers and find the difference between their sum and their average.

import java.util.*;
class Difference
{
	public static void main(String arr[])
	{
		Scanner sc=new Scanner(System.in);
		int a,b,c,s;
		float av,d;
		System.out.println("Enter 3 integers:");
		a=sc.nextInt();
		b=sc.nextInt();
		c=sc.nextInt();
		s=a+b+c;
		av=s/3f;
		d=s-av;
		System.out.println("Sum="+s);
		System.out.println("Average="+av);
		System.out.println("Difference b/w Sum and Average = "+d);
	}
}

Enter 3 integers:

4

5

6

Sum=15

Average=5.0

Difference b/w Sum and Average = 10.0
