java - 需要帮助编写文字游戏

Question

我在 Eclipse 中收到错误消息:

The type of the expression must be an array type but it resolved to Player.

我创建了一个对象 Player。用户通过 JOptionPane 输入他们想要的玩家数量。我正在尝试将玩家姓名存储在数组中。

 public class Project3 {
 public static void main(String[] args){

  String input = JOptionPane.showInputDialog("Enter the number of players: ");
  int numPlayers = Integer.parseInt(input);
  Player nameOfPlayers;

  for(int i = 0; i < numPlayers; i++){
   nameOfPlayers[i] = new Player(JOptionPane.showInputDialog("Enter the number of players: "));
   if (input == null || input.equals(" ")) throw new IllegalArgumentException("Must enter valid name!!!");

  }

 }

这是我的类(class)玩家:

public class Player {
 private String name;

 public Player(String name){
  if(name == null || name.equals(" "))
   throw new IllegalArgumentException("Must enter a name. ");

  this.name = name;

 }


 public void addWord(Word w){

 }
 public int getScore(){

 }
}

您尚未创建数组。 也许您的意思是 Player [] nameOfPlayers = new Player[somevalue];
