如何在Java中初始化对象数组

Question

我想初始化一个BlackJack游戏的Player对象数组。我已经阅读了很多有关初始化原始对象（例如int数组或字符串数​​组）的各种方法的信息，但是我无法将此概念理解为我在此处尝试做的事情（见下文）。我想返回一个初始化的Player对象数组。要创建的播放器对象的数量是一个整数，我向用户提示。我以为构造函数可以接受一个整数值并在初始化Player对象的一些成员变量时相应地命名播放器。我想我很亲密，但仍然很困惑。

static class Player
{
    private String Name;
    private int handValue;
    private boolean BlackJack;
    private TheCard[] Hand;

    public Player(int i)
    {
        if (i == 0)
        {
            this.Name = "Dealer"; 
        }
        else
        {
            this.Name = "Player_" + String.valueOf(i);
        }
        this.handValue = 0;
        this.BlackJack = false;
        this.Hand = new TheCard[2];
    } 
}
private static Player[] InitializePlayers(int PlayerCount)
{ //The line below never completes after applying the suggested change
    Player[PlayerCount] thePlayers;
    for(int i = 0; i < PlayerCount + 1; i++)
    {
        thePlayers[i] = new Player(i);
    }
    return thePlayers;
}

差不多了 只需：

Player[] thePlayers = new Player[playerCount + 1];

并让循环成为：

for(int i = 0; i < thePlayers.length; i++)

请注意，Java约定规定方法和变量的名称应以小写字母开头。

更新：将您的方法放在类主体中。
