Adding a player name

I'm trying to get the player to enter their name before my game starts playing. However I'm getting the error

"method addName in glass Gamme cannot be applied to given types;

required: java.lang.String[]; found no arguments

public class Game 
{
    private Parser parser;
    private Room currentRoom;
    private String playerName;

    public Game() 
    {
        createRooms();
        parser = new Parser();

        addName();
        play();       
    }


    private static void addName(String[] args)
    {
       Console console = System.console();
       String playerName = console.readLine("Welcome, what is your name? ");

     if (playerName.length() >= 2) {
         System.out.println("Hello" + playerName);
     }   
     else {
          String playerName = console.readLine("Not and ok name, re-enter name");
      }
    }
    }
}

private static void addName(String[] args) {...}

requires an input of an array of Strings. As it is now, you are not supplying that input when you call the method addName().

Just remove the input argument from the method signature:

private static void addName() {...}

Hi Rebecca,

That works thank you so much. I am however getting another error now when the game actually runs in the terminal:

java.lang.NullPointerException at Game.addName(Game.java:43) at Game.<init>(Game.java:34)

Don't have the line numbers. What is on those two lines, 43 and 34?
