Question

我想我在这里混淆了一些东西。在players.add（名字）我的指示是...... “

添加名为addPlayer新方法。而应采取的String玩家名称作为论点。使用字符串创建一个新的播放器，并把它添加到球员名单。“

package edu.htc.java1.phrasegame;
import edu.htc.java1.phrasegame.model.*;

import java.util.ArrayList;

public class PhraseGameController { 

    private Phrase currentPhrase; 
    private ArrayList<Character> guessed; 
    private ArrayList<Player> players;  //2


    PhraseGameController Player = new PhraseGameController();   //3


    public void addPlayer(String name) {
        Player players= new Player(name);
        players.add(name);                    //// <<< Error Is Here

    }

    public ArrayList<Player> getPlayers() {
        return players;
    }                                //4







    public boolean doPlayerGuess(Character play) {

        Character guess = Character.toUpperCase(play);
        if(guessed.contains(play)){
            throw new IllegalStateException("the letter was already guessed");
    } else if (!String.valueOf(play).matches("[A-Z]")) {
        throw new IllegalStateException("the guess should be a letter from AZ");
    }

    guessed.add(guess); 
    return currentPhrase.guessLetter(guess);

    }







    public PhraseGameController(){
    currentPhrase = new Phrase("This is only a test");
    guessed = new ArrayList<Character>();       
    }



     public Phrase getCurrentPhrase() {  
        return currentPhrase;
    }
    public void setCurrentPhrase(Phrase currentPhrase) {
        this.currentPhrase = currentPhrase;
    }

    public void setGuessedLetters(ArrayList<Character> guessed) {
        this.guessed = guessed;
    }
    public ArrayList<Character> getGuessedLetters() { 
        return guessed;
    }
}

and my player class..

    package edu.htc.java1.phrasegame.model;

public class Player {

public int currentScore;
public int highScore;
public String name;


public String getPlayerName() {
    return "Me";
}
public Player(String getName) {
    getName = "Me";
}
public int modifyScore(int points) {
    currentScore = points + currentScore;
    return currentScore;
}

 public void finalizeScore() {
     if ( currentScore >= highScore){
         highScore = currentScore;
     }  
         currentScore = 0;

 }



// Getters and setters
public int getCurrentScore() {
    return currentScore;
}
public int getHighScore() {
    return highScore;
}


}

Answer 1

试试这个：

public void addPlayer(String name) {
    players.add(new Player(name)); // add the player object not name
}

Answer 2

您需要添加Player对象而不是String名称，如：

public void addPlayer(String name) {
    Player player = new Player(name);
    players.add(player); // add the player object not name
}

对于类型播放器，方法add（String）未定义
