This class will allow a user to enter 5 scores into an array. It will then rearrange the data in descending order and calculate the mean for the data set. Attributes: data[]— the array which will contain the scores mean — the arithmetic average of the scores Methods: Average — the constructor. It will allocate memory for the array. Use a for loop to repeatedly display a prompt for the user which should indicate that user Copyright © 2019 Pearson Education, Inc., Hoboken NJ should enter score number 1, score number 2, etc. Note: The computer starts counting with 0, but people start counting with 1, and your prompt should account for this. For example, when the user enters score number 1, it will be stored in indexed variable 0. The constructor will then call the selectionSort and the calculateMean methods. calculateMean — this is a method that uses a for loop to access each score in the array and add it to a running total. The total divided by the number of scores (use the length of the array), and the result is stored into the mean. toString — returns a String containing data in descending order and the mean. selectionSort — this method uses the selection sort algorithm to rearrange the data set from highest to lowest.
