Question

I have the following code:

public static void main(String[] args) {
  Player players[] = new Player[2];
  Scanner kb = new Scanner(System.in);
  System.out.println("Enter Player 1's name");
  players[0] = new Player(kb.nextLine());
  System.out.println("Enter Player 2's name");
  players[1] = new Player(kb.nextLine());
  System.out.println("Welcome "+ players[0].getName() + " and " + players[1].getName());    
}

It is meant to create a new player object and store the name of the player, while keeping all the objects in the array.

Here is the player class:

public class Player {
  static String name;
  public Player(String playerName) {
    name = playerName;
  }

  public String getName(){
    return name;
  } 
}

What actually happens is that it works when I just have 1 object, but when I have 2, each element in the array is the same as the second. When I have 3 objects in the array, each element is the same as the 3rd, etc.

I’m not sure why this is happening, or how to correct it, and it’s been baffling me for hours :/

Its because of the static field. Statics are used across object instances. They are stored at class level.

Below code would work:

class Player
{
    String name;

    public Player(String playerName)
    {
        name = playerName;
    }

    public String getName()
    {
        return name;
    }
}
