CS101 Lab 9 Solution

For all labs, your solutions must conform to the CS101 style guidelines!
All data and results should be stored in variables (or constants where appropriate) with meaningful names.
The objective of this lab is to learn how to use Arrays and ArrayLists. An array is a container object that holds a fixed number of values of a single type. When you need an array-like data structure that offers dynamic resizing, you would usually use an ArrayList. An ArrayList is an array that resizes itself as needed. Remember that analyzing your problems and designing them on a piece of paper before starting implementation/coding is always a best practice.
0. Setup Workspace
Start VSC and open the previously created workspace named labs_ws. Now, under the labs folder, create a new folder named lab9.
In this lab, you are to have five Java classes/files (under labs/lab9 folder) as described below. A sixth Java file containing the revision should go under this folder as well. We expect you to submit 6 files, including the revision, without compressing them. Do not upload other/previous lab solutions in your submission. Outputs of sample runs are shown as brown whereas the user inputs are shown in blue color.
1. Player Class
Create a new/empty file to define a class named Player. This class defines the details of a football player in the application.

- marketValue: The current market value of the player (int)
Methods:
- Constructor:
- Creates the player to be used.
- Takes name, age, nationality, jerseyNumber, position, and marketValue. There are restrictions where age and marketValue must be positive, and jerseyNumber must be between 1 and 99, inclusive.
- Initializes the data members name, age, nationality,jerseyNumber, position, marketValue.

- toString method
- Override the toString method to get an understandable string representation of a player object, showing the player’s name, age, nationality, jersey number, position, and market value.
Sample run:
Player p = new Player("Raheem Sterling", 27,"England", 17, "Left Wing", 70000000)); System.out.println(p);
Raheem Sterling 27 England 17 Left Wing 70,000,000
2. Team Class
Create a new/empty file to define a class named Team. This class defines the details of a team in the application.

- Accessor methods:
- You need to implement methods to access the data variables ID, name, averageAge, and marketValue.
- Team methods:
- playerExists : returns true if a player with a specific jersey number exists in the team.
- addPlayer : takes a Player object as parameter and adds this player to the team if the player does not exist in the team and the player is a citizen of that country
- removePlayer: removes the player from the team with the specific jersey number
- toString: Override the toString method to return an informative representation of the team including team ID, name, average age, total market value, and players in the team.
Sample output for a Team object:
Team turkiye = new Team(38, "Türkiye");
Player p1 = new Player("Altay Bayindir",24, "Türkiye", 1, "Goalkeeper", 13000000); Player p2 = new Player("Çaglar Söyüncü",26, "Türkiye", 4, "Centre Back", 22000000); turkiye.addPlayer(p1); turkiye.addPlayer(p2);
System.out.println(turkiye);
=================================================================================
= Team Details = =================================================================================
ID: 38
Team: Türkiye
Average Age: 25
Market Value: 35,000,000
Squad is composed of following players:
--------------------------------------------------------------------------------Name Age Nationality Number Position Market Value
---------------------------------------------------------------------------------
Altay Bayindir 24 Türkiye 1 Goalkeeper 13,000,000
Çaglar Söyüncü 26 Türkiye 4 Centre Back 22,000,000
=================================================================================
3. Game Class
Your next task is to create a new/empty file to define a class named Game that defines the details of a game/match in the application.
Instance Data Members:
- teams: Array of Team objects playing the game (Array)
- goals: Array of integers indicating the goals scored by respective teams (Array)
Methods:
- Constructor:
- Registers the game to the system.
- Takes team1, team2, team1Goals, and team2Goals, where goals must be positive and teams must exist.
- Initializes the data members teams and goals.
- Accessor methods:
- You need to implement a method to access the data variable teams.
- Game methods:
- getTeamPoints: returns the points obtained from this game for a given team with its team ID.
- toString: Override the toString method to return an informative representation of the game, including team names and the goals of the respective teams.
Sample output for a Game object:
Team germany = new Team(6, "Germany");
Team turkiye = new Team(38, "Türkiye");
Game g1 = new Game(turkiye, germany, 3, 2);
System.out.println(g1);
Türkiye vs. Germany: 3-2
4. Group Class
Create a new/empty file to define a class named Group. This class defines the details of a group in the world cup qualifiers.
Instance Data Members:
- name: The name of the group (String)
- groupSize: The size of the group (int)
- numberOfTeams: The number of teams currently added to the group (int)
- teams: Array of Team objects playing the game (Array)
- games: Array of {Array of Game objects} indicating the games played between teams in the group ( 2D Array)
- points: Array of points received (Array)
Methods:
- Constructor:
- Registers the group to the system.
- Takes a name and a positive groupSize.
- Initializes the data members name, groupSize, numberOfTeams, teams, games, and points.
- Accessor methods:
- You need to implement methods to access the data variables name, groupSize, and numberOfTeams.
- Group methods:
- teamExists : returns true if the team with the given ID exists in the group
- addTeam: adds a team to the group if the team does not already exist in the group and there is room in the group
- addGame: adds a game to the group by updating the individual team game properties in the group captured by the games data member. The game is added only if both teams of the game belong to the same group. Furthermore, we assume that there is only one game between the teams (there is no concept of Home vs. Visitor in the world cup). Additional games added between the same teams will be ignored. When the game is added, points for the teams are updated accordingly.
- toString: Override the toString method to return an informative representation of the group, which displays the standings within the group according to the points so far.
Sample output for a Group object:
Group B = new Group("B", 3);
Team germany = new Team(6, "Germany");
Team turkiye = new Team(38, "Türkiye");
Team england = new Team(34, "England");
B.addTeam(england); B.addTeam(germany);
B.addTeam(turkiye);
Game g1 = new Game(turkiye, germany, 3, 3);
Game g2 = new Game(turkiye, england, 2, 0);
B.addGame(g2);
B.addGame(g1);
System.out.println(B);
==================================
= Group B Standings =
==================================
1. Germany ( 6 ) 4 2. England ( 34 ) 1
3. Türkiye ( 38 ) 0
==================================

5. Main Class
Download the Java class provided to you with the Qatar22 name. This class already defines the three teams with players for you, namely, Türkiye, England, and Germany. Furthermore, a group with 4 teams is created with these three teams added. Your main method will start with this already-filled data. Then, you will provide a menu for the user to interact with Player, Team, Game, and Group objects. Create the Qatar22 app where user will be able to:
- create a new team,
- display a team,
- add a player to a team,
- remove a player with ID from a team,
- add a game to the group,
- display standings in the group,
- exit the application
Note: You need to check user input for the correctness and perform the modifications and updates if the inputs are valid. For example, if the group is already full, you will not accept adding a new team to the group. Or if a player with a jersey number already is on the team, you should respond to the user indicating that “a player with that jersey number is already in the team.” Users should know what is going on in the application. We have shown only some problematic input cases, but you should consider all possible scenarios. The specific conditions are given in each class for each property. You do not need to check for the correctness of input if it is not specified in the class.
while( there are teams not displayed yet){ find the team that is not displayed yet with the maximum points and display it
