$4\mathrm{.}15$ LAB: Varied amount of input data

Statistics are often calculated with varying amounts of input data. Write a program that takes any number of non$-$negative integers as input,

and outputs the max and average. A negative integer ends the input and is not included in the statistics. Assume the input contains at least

one non$-$negative integer.

Output the average with two digits after the decimal point followed by a newline, which can be achieved as follows:

System.out.printf$("\%\mathrm{.}2$f

$",$ average$)$;

Ex: When the input is:

$15,20,0,3,-1$

the output is:

$209\mathrm{.}50$

$538068\mathrm{.}4028272.$qx$3$zqy$7$
