静态ArrayList - 填充增强循环

Question

我面临着静态arraylists的问题.

我有一个带字符串的播放器类.

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

我有一个静态的玩家角色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arraylist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

谁能帮助我理解我做错了什么？

确保Player类看起来如下:

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