I have a problem with my code in java, replit. When I run my code in the console, the output for the csv file is always the random ID number, null, 0,0,0. I don't want null, 0,0,0. null,0,0,0 reflects name, totalgames, totalguesses, and bestgame. When I run my program it doesn't give the actual value of totalgames, totalguesses, and bestgame just 0,0,0 every time. Could you fix this? Also name is null because I haven't asked for the player's name, so I would like you to include that as well in this code. Here is the code, each class in seperate files in replit: import java.util.Scanner; import java.util.Random; public class Main { public static void main(String[] args) { Scanner console = new Scanner(System.in); Random random = new Random(); Game game = new Game(console, random); game.startGame(); console.close(); } } import java.util.Scanner; import java.util.UUID; public class Player { private UUID id; private String name; private int totalGames; private int totalGuesses; private int bestGame; public Player() { this.id = UUID.randomUUID(); } public UUID getId() { return id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getTotalGames() { return totalGames; } public void setTotalGames(int totalGames) { this.totalGames = totalGames; } public int getTotalGuesses() { return totalGuesses; } public void setTotalGuesses(int totalGuesses) { this.totalGuesses = totalGuesses; } public int getBestGame() { return bestGame; } public void setBestGame(int bestGame) { this.bestGame = bestGame; } public int playGame(Scanner console, int answer) { System.out.println("I'm thinking of a number between 1 and " + Game.MAX + "..."); int guesses = 0; while (true) { System.out.print("Your guess?
