我正在用Java做一个小游戏,用于学校目的。
现在,我要计算播放器的数量,代码如下:

    Player player1;
    player1 = new Player();

    player1.name = "Name1";
    player1.score = 0;
    player1.lives = 100.0;

    Player player2;
    player2 = new Player();

    player2.name = "Name2";
    player2.score = 0;
    player2.lives = 50.0;

最佳答案

在播放器中,使用static variable计数在播放器构造函数中递增。

private static int playerCount = 0;

//constructor
Player(){
  playerCount++;
}
