Java Program
Write a class called Stats that will hold and/or compute various statistics. The class will work with integer values, including negative numbers and 0. There is no need to use arrays for this project. You will need loops and if statements. You will implement the following methods: void add (int n) int getMin() int getMax () int getCount) int computeSum () double computeAvg () int getNumPositive ()return the count of positive numbers seen so far int getNumNegative ()return a count of negative numbers seen so far int getNumZero () void reset () include n as a new entry in the "collection return the smallest number seen so far return the largest number seen so far return the count of numbers seen so far return the sum of the numbers seen so far return the average of the numbers seen so far return a count of zeros seen so far reset the data to reflect no entries Write a main program to exercise this class. Your program should have the usual main method, as well as a second method declared as private static void displayResults (Stats stats) f. )Explanation / Answer
