Question

Modify the method so that instead of manually making teams, it reads it from a text file called TeamsList.txt. Everything must be done in this method.

public void make_test_teams() {
List<Team> teams = new ArrayList<Team>();

Player burns = new Player("George Burns", "George");
Player allen = new Player("Gracie Allen", "Gracie");
List<Player> ba = new ArrayList<Player>();
ba.add(burns); ba.add(allen);
Team burns_and_allen = new Team("Burns and Allen", ba);
teams.add(burns_and_allen);

Player abbott = new Player("William Abbott", "Bud");
Player costello = new Player("Louis Cristillo", "Lou");
List<Player> ac = new ArrayList<Player>();
ac.add(abbott); ac.add(costello);
Team abbott_and_costello = new Team("Abbott and Costello", ac);
teams.add(abbott_and_costello);

Player chico = new Player("Leonard Marx", "Chico");
Player groucho = new Player("Julius Marx", "Groucho");
Player harpo = new Player("Adolph Marx", "Harpo");
List<Player> mb = new ArrayList<Player>();
mb.add(chico); mb.add(groucho); mb.add(harpo);
Team marx_brothers = new Team("Marx Brothers", mb);
teams.add(marx_brothers);

store_teams(teams);
   }

the text file looks like

team: "Burns and Allen"
player: fullname: George Burns, nickname: George
player: fullname: Gracie Allen, nickname: Gracie

team: "Abbott and Costello"
player: fullname: William Abbott, nickname: Bud
player: fullname: Louis Cristillo, nickname: Lou

team: "Marx Brothers"
player: fullname: Leonard Marx, nickname: Chico
player: fullname: Julius Marx, nickname: Groucho
player: fullname: Adolph Marx, nickname: Harpo

Updated Method:

public void make_test_teams() {
   List<Team> teams = new ArrayList<Team>();

   // Reading data from file
   try {
       //Scanner class object to read data from file
       Scanner reader = new Scanner(new File("TeamsList.txt"));
      
       //Reading data from file
       while(reader.hasNext()) {
           String line1 = reader.nextLine();
           String line2 = reader.nextLine();
           String line3 = reader.nextLine();
          
           //Fetching Team name
           String teamName = line1.split(": ")[1]
           //Replacing double quotes
           teamName = teamName.replaceAll("^\"|\"$", "");
          
           //For player 1
           //Fetching full name
           String p1fullName, p1nickName;
           p1fullName = ((line2.split(", "))[0]).split(": ")[2]
           //Replacing comma
           p1fullName = p1fullName.replaceAll(",", "");
          
           //Fetching nick name
           p1nickName = ((line2.split(", "))[1]).split(": ")[1]
          
           //For player 2
           //Fetching full name
           String p2fullName, p2nickName;
           p2fullName = ((line3.split(", "))[0]).split(": ")[2]
           //Replacing comma
           p2fullName = p2fullName.replaceAll(",", "");
          
           //Fetching nick name
           p2nickName = ((line3.split(", "))[1]).split(": ")[1]
          
           //Creating objects
           Player p1 = new Player(p1fullName, p1nickName);
           Player p2 = new Player(p2fullName, p2nickName);
          
           List<Player> ba = new ArrayList<Player>();
           ba.add(p1); ba.add(p2);
          
           Team teamN = new Team(teamName, ba);
           teams.add(teamN);
       }
      
       store_teams(teams);
      
       //Closing file
       reader.close();
   }
   catch(IOException ex) {
       System.out.println(ex);
   }
   catch(FileNotFoundException ex) {
       System.out.println(ex);
   }
}
