Write a program that reads a set of floating-point values. Ask the user to enter the values (prompting only a single time for the values), then print:

-the average of the values.

-the smallest of the values.

-the largest of the values.

-the rage, that is the difference between the smallest and largest.

Your program should use a class DataSet. That class should have a method public void add(double value) and methods getAverage, getSmallest, getLargest, and getRange.

Use the following basic constructor and then create a Tester:

public class DataSet { double sum, count, max, min; public DataSet() { } public void add(double number) { // provide code for this method } public double getAverage() { // provide code for this method } // you can define more methods too as you need them public boolean hasData() { // provide code for this method }
