You may reuse your player object from program 1. See that assignment for the requirements for a single player. We are adding additional computations to this program. Each line of the data file will contain one player's name and stats. The format is similar as before, but we are adding in three more fields: firstname lastname plateappearances atbats singlas doubles triples homeruns walks hitbypitch You may assume there are no errors in the data. Iwill not leave data out or put non-numeric data in numeric fields, You must read until the end of the file is found. New Requirements You are to implement a PlayerList data structure/data type that stores players using an internal array in the class. Add players to the List as they are read in from the data file. You may assume that there are no more than 75 players in a single data file. You must implement the following operations on your List along with any other utility functions you might need. You may also need to add operations to your player to encapsulate i/o operations to the Operations for PlayerList Default Constructor .Add a player to the List add items in the order they were found in the file. No sorting is necessary in this version of the program. .Iterate through the List so that you can get each item out for printing o You must implement hasNext) and getNext) on your list for this to work .Clear out the list to make it empty Test if a list isFull Get the size of the list .Compute the team's batting average as an average of the player's individual averages New Operations for the player objects Add methods needed to get the additional compute values: EX: getOnBasePercentage0 etc We are going to compute slugging percentage as well as the batting average. The slugging percentage is a weighted average. It is computed by: . singles 2 doubles +3 triples +4 number of at bats homeruns slugging O Type here to search 11:42 PM 9/14/2018Explanation / Answer
