Question

I am getting an error message in Eclipse:

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

I have created an object Player. The user through the JOptionPane enters how many players they want. I am trying to store the players names in an array.

 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!!!");

  }

 }

Here’s is my Class Player:

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(){

 }
}

Answer 1

You’re using the old value of input (from when you were asking for the number of players). You probably want something more like this:

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

Edit: Based on the error message you posted, the problem is that nameOfPlayers isn’t an array, but you’re treating it like one. Try Player[] players = new Player[numPlayers]; instead.
