java - 静态ArrayList - 填充增强循环

Question

我遇到静态数组列表的问题。

我有一个需要字符串的玩家类。

public Player (String s) {    
    myPlayerName = s;
    myPlayerScore = 0;
}

我有一个静态的玩家数组列表和一个静态的字符串数组。

static final ArrayList <Player> MY_PLAYER_LIST = new ArrayList<Player>();
static final String [] TEST_PLAYER_LIST = {"adam", "eve", "john", "mary",};

我有一个填充数组列表的函数。

public void buildPlayerList () {    
    System.out.println("Before - " + MY_PLAYER_LIST.size());
    for (String temp: TEST_PLAYER_LIST) {
        Player tempPlayer = new Player(temp);
        MY_PLAYER_LIST.add(tempPlayer);
        System.out.println("Player: " + tempPlayer.getMyPlayerName());
    }
    System.out.println("After - " + MY_PLAYER_LIST.size());
    for (Player temp: MY_PLAYER_LIST) {    
        System.out.println(temp.getMyPlayerName());    
    }
}

但是我得到的输出是；

Before - 0
Player: adam
Player: eve
Player: john
Player: mary
After - 4
Player: mary
Player: mary
Player: mary
Player: mary

任何人都可以帮助我理解我做错了什么吗？

确保 Player 类如下所示:

public class Player{
    private  String myPlayerName;
    private int myPlayerScore;
    public Player (String s) {    
        myPlayerName = s;
        myPlayerScore = 0;
    }
    public String getMyPlayerName() {
        return myPlayerName;
    }           
}
