Question

Assume you have the following text file:

players.txt

Pikachu,10
Geodude,50
Zubat,75
Marowak,37

Each line contains a player's name and starting health, separated by a comma (,).

Write a method called createPlayers which reads the lines from that file and returns an array of Player objects matching the properties in the input file. Assume you have access to the Inclass we've been using to read text from an input file, and that it has been correctly imported at the top of your program. using java programming language.

Hello, here is the answer to your question:

import java.io.*;
import java.util.*;
class Player
{
String name;
String Health;

Player(String name,String Health)
{
    this.name=name;
    this.Health=Health;
}

static ArrayList<Player> createPlayers() throws IOException
{
    ArrayList<Player> players = new ArrayList<Player>();
    File f = new File("players.txt");
    try (BufferedReader br = new BufferedReader(new FileReader(f)))
    {
    String line;
    while ((line = br.readLine()) != null)
    {
       String[] lineSplit = line.split(",");
       players.add(new Player(lineSplit[0],lineSplit[1]));
    }
  
    }
    return players;
}
}
class Main
{



public static void main(String[] args) throws IOException
{
    ArrayList<Player> answer = Player.createPlayers();
    for(int i=0;i<answer.size();i++)
    {
      Player player = answer.get(i);
      System.out.println("Player name:"+ player.name + ", Player health" + player.Health);
    }
  
}
}

What I have exactly done is created a Player class and created a static method of createPlayer() as asked. The main program has a driver code to test the method.

Hope this helps!
