Java program to find sum, average and modulus by 3, of three numbers by(aol.com)

import java.util.*;
class average
{
public static void main (String args[])
{
Scanner in = new Scanner (System.in);
double a,b,c,sum=0;
double mod,avg;
System.out.print ("\n\t Enter first number = ");
a=in.nextDouble();
System.out.print ("\n\t Enter second number = ");
b=in.nextDouble();
System.out.print ("\n\t Enter third number = ");
c=in.nextDouble();
sum=a+b+c;
avg=sum/3;
mod=sum%3;




System.out.println ("\n\t Sum of the numbers = "+sum);
System.out.println ("\n\t Average of the numbers = "+avg);
System.out.println ("\n\t Modulus of the sum of numbers by 3 = "+mod);
}
