Java for循环创建n个对象

Question

我需要一些帮助。我想创建一个 for 循环来创建一个类的 n 个对象，然后将它们添加到一个数组列表中。像这样的:

//Player is a custom class 
ArrayList<Player> numberofPlayersArray;
numberofPlayersArray = new ArrayList<Player>();

//n is a variable for the number of Player class objects that I want to create
  for(int i = 0; i < n; i++)
  {

    //this is what I can come up with but I am missing something 

     Player p;
     p = new Player
     numberofPlayersArray.add(p);

    }

任何帮助将不胜感激

Answer 1

//Player is a custom class 
ArrayList<Player> numberofPlayersArray = new ArrayList<Player>(n);

//n is a variable for the number of Player class objects that I want to create
for(int i = 0; i < n; i++) {

     Player p = new Player();
     numberofPlayersArray.add(p);
}

请注意，最好用大小初始化 ArrayList，如果它是已知的(如您的情况)
