For this lab you will write a Java program that produces a simple formatted report. The program will prompt the user to enter a file name. This file must contain information in a specific format (detailed below). Each "block" of the file contains information for one player in a competition -- the name of the player followed by a number of different scores that that player achieved. The program should find each player's average score, median score and best and worst scores and display them in a line on the final summary report. The program should also determine which player has the highest average score and which player has the lowest average score. (HINT: Consider storing information in ArrayLists to make the final summaries easier to produce).
For this assignment you should start with the following "skeleton" of Java code. Import this into your Eclipse workspace and fill in the methods as directed. The skeleton provided for this assignment is much more "skeletal" than previous assignments. For this assignment you MUST add at least two extra methods beyond the methods defined in the skeleton. These methods must not be trivial one or two line methods, but a real breakdown of the code. Consider adding methods to write the formatted report, or helper methods for reading the input file or computing necessary values. Feel free to add any methods you find useful, and make sure that you add comments indicating what they do following the form of the rest of the comments in the code.

public class Project11 { public static void main(String[] args) { // Fill in the body } // Given a Scanner as input read in a list of integers one at a time until a negative // value is read from the Scanner. Store these integers in an ArrayList<Integer> and // return the ArrayList<Integer> to the calling program. private static List<Integer> readNextSeries(Scanner inScanner) { // Fill in the body } // Given a List<Integer> of integers, compute the median of the list and return it to // the calling program. private static int getMedian(List<Integer> inList) { // Fill in the body } // Given a List<Integer> of integers, compute the average of the list and return it to // the calling program. private static int getAverage(List<Integer> inList) { // Fill in the body }
