G 4.16 Write a program that takes any number of non-negative integers as input, and outputs the average and max. A negative integer ends the input and is not included in the statistics. Ex: When the input is:

import java.util.ArrayList;

import java.util.Scanner;

import java.util.Collections;

public class num4 {

   public static void main(String[] args) {

       int sum = 0;

       Scanner in = new Scanner(System.in);

       System.out.println("Enter number");

       int num = in.nextInt();

       ArrayList<Integer> list = new ArrayList<>();

       while (num >= 0){

       list.add(num);

       System.out.println("Enter another positive number, enter a negative to stop");

       num = in.nextInt();

       }

       int maximum = Collections.max(list);

       int listSize = list.size();

       for(int i:list){

           sum = sum+i;

       }

       double average = (double) sum/listSize;

       System.out.println("Maximum number entered is "+maximum);

       System.out.println("Average of the number is "+average);

   }

}
