using java with comments please and no arrays

1. (Sum and average of a set of integers entered by the user) Write a Java program that reads an unspecified number of integers (but no more than twenty, total), determined how many of those were positive vs. negative, and computes the total sum and the average of the entered values. The program stops prompting the user to enter more integers once either 0 has been entered as input, or if there have been twenty entered (non-zero) values. You are encouraged, but not strictly required to use methods. Show the output of your Java program on five sets of inputs, total. Three sets are your choice, under the constraint that there should be at least five input non-zero values before the first 0 is encountered. The remaining two test runs should be on the following input sequences: 1 2-1 35 10 -5 -10 0 1 -1 2-2 3-3 4-4 5 -5 0
