  public static void main(String args[]) {
    Scanner conin = new Scanner(System.in);

    int count = 0;

    System.out.println("Enter numbers to average.");

    while (conin.hasNext()) {
      if (conin.hasNextDouble()) {
        System.out.println(conin.nextDouble()); 
        count++;
      }
      if(count == 3){
        System.exit(0);
