CSCI 2110 Data Structures and Algorithms – Fall 2015 Assignment No. 2 Date Given: Monday, October 12, 2015 Date Due: Monday, October 26, 2015, 11.55 p.m. (5 minutes to midnight) This assignment is on the application of Unordered Lists. You will need the source codes for Node.java, LinkedList.java and List.java. Download them (they are given next to the assignment link). You will also need the text file nhlstats.txt (download this file as well). Before you begin this assignment, it will be useful to study the Expense.java, ExpenseList.java and ExpenseListDemo.java programs that were discussed in the lectures. You will also need knowledge of File Processing and String Tokenizer (from CS 1101). You are given the raw scores of various NHL players’ regular hockey games in the file nhlstats.txt. The file has data organized in the following manner: Name Pos Team GP G A PIM SOG GWG Marchand LW BOS 45 18 18 27 91 5 Eberle C EDM 48 16 21 16 133 3 … etc. Note: The first row is not there in the actual nhlstats.txt file. It just tells you what each column stands for. The meanings of abbreviations are as follows: Pos stands for Position. In this column, C means Center, LW means Left Wing, RW means Right Wing, LD means Left Defense, RD means Right Defense, and G means Goalie. GP stands for Games Played. G stands for Goals scored. A stands for Assists. PIM stands for Penalties In Minutes SOG stands for Shots on Goal GWG stands for Game Winning Goals. So, for example, in the above file, Marchand plays Left Wing, belongs to team BOS (Boston Bruins), played 45 games during the season, scored 18 goals, had 18 assists, spent 27 penalty minutes, had 91 shots on goal and 5 game winning goals. Now, from these numbers, hockey statisticians calculate interesting information, such as the following: • P (Points: this equals Goals plus Assists). For example, Marchand has 36 points and Eberle has 37 points. • PG (Points per Game: this equals P divided by GP). For example, Marchand’s PG is 36/45 = 0.80 and Eberle’s PG is 37/48 =0.77. (Caution: Integer division!) • PCT (Shooting percentage: this equals goals divided by shots on goal multiplied by 100). For example, Marchand’s PCT is (18/91)*100 = 19.8 and Eberle’s PCT is (16/133)*100 = 12.0. (Caution: Integer division!). Here is what your program should do. Follow these steps. 1. First create a class called PlayerRecord.java that has all the instance variables for one player (Name, Position, Team, GP, G, A, PIM, SOG, GWG). Also include instance variables P, P/G, and PCT for that player. Add the constructor and associated get, set and toString methods. Also add the following methods: a. Method that calculates the player’s P and sets that value b. Method that calculates the player’s PG and sets that value c. Method that calculates the player’s PCT and sets that value Note: Use the DecimalFormat class to round off P/G and PCT to two decimal places. public class PlayerRecord { …. } 2. Create a class called NHLStats.java that has as attribute an unordered list of PlayerRecord objects and a constructor to create such an empty unordered list. This class can use methods from the List class, but it cannot use methods from the LinkedList class or Node class. public class NHLStats { private List playerlist; …… } In this class, include the following methods: Constructor to create an empty list (of PlayerRecords) add a PlayerRecord to the list check if the list is empty get the first item get the next item enumerate Also add the following methods: 1. Who is the player with the highest points? : Method that displays the player’s name with the maximum number of points and his team’s name. Note: If more than one player has the largest number of points, display all the players and their teams. 2. Who is the most aggressive player? : Method that displays the name of the player who had the maximum number of penalty minutes, his team name and his position. Same note as in 1 applies. 3. Who is the most valuable player (MVP)? : Method that displays the name of the player who scored the most number of game winning goals and his team’s name. Same note as in 1 applies. 4. Who is the most promising player? : Method that displays the name of the player who took the most number of shots on goal and their team names. Same note as in 1 applies. 5. Which team has the most penalty minutes? : Method that displays the name of the team that had the most penalty minutes (sum of all penalty minutes of all players in that team). Same note as in 1 applies. 6. Which team has the most game winning goals? : Method that displays the name of the team that had the most number of game winning goals (sum of all GWGs for that team). Same note as in 1 applies. 7. Which team has the least game winning goals? : Method that displays the name of the team that had the least number of game winning goals (sum of all GWGs for that team). Same note as in 1 applies. You may add other methods as needed. Note: If you find it useful, you can create one more class called the Team class and store the attributes of each team. This will help you search and get answers specific to a team. 3. Write a client program NHLListDemo.java with the main method that reads the file nhlstats.txt and prints the following into another file nhlstatsoutput.txt. Note: When you read data from the file, each line is read as a String. Use StringTokenizer to break it down into individual components. Note that the input file has rows in which the items are delimited by tabs. So you need to use the StringTokenizer in a manner similar to the following: token = new StringTokenizer(line, “t”); Also to convert a String to an integer value, use Integer.parseInt(…). Your output should be similar to the format given below: NHL Results Summary Name Position Team GP G A PIM SOG GWG P P/G PCT Marchand LW BOS 45 18 18 27 91 5 36 0.80 19.8 Eberle C EDM 48 16 21 16 133 3 37 0.77 12.0 …… etc. Players with highest points and their teams: … Most aggressive players, their teams and their positions: … Most valuable players and their teams: … Most promising players and their teams: … Teams that had the most number of penalty minutes: …. Teams that had the most number of game winning goals: …. Teams that had the least number of game winning goals: …. Submit a zip file containing the following source codes: PlayerRecord.java NHLList.java NHLListDemo.java and the output text file: nhlstatsoutput.txt
