Add of an object via an input (arrayList)

Question

Currently, I have 2 objects and I would like to enter a new object.

List<Player> players = new ArrayList<Player>();
players.add(new Player("Eric", 31, true));
players.add(new Player("Juliette", 28, false));

I am looking for a solution on StackOverFlow like below: But, I don't understand my error.

How to add an object into ArrayList in java

Here is my method:

public static void addPlayer(List <Player> players){
    Scanner inputPlayer = new Scanner(System.in);
  
    System.out.print("Enter your player please : ");
    String name = inputPlayer.next();
    Player.add(name);

}

My error is -> Main.java:75: error: cannot find symbol Player.add(name); text

I don't understand my problem??

Player.add(name)

Here is my method called:

case 4 : System.out.println("Option 4 - : ");
         addPlayer(players);
break;

My Class Player

public class Player {

  public String name;
  public int age; 
  public boolean sex;

  public Player(String name, int age, boolean sex){
    this.name = name;
    this.age = age;
    this.sex = sex;
  }

Thank you in advance for your help.

Hi @eric, you are calling Player.add instead of your parameter name: players.add — gtgaxiola

Hi @ gtgaxiola, I always have the same problem Main.java:75: error: incompatible types: String cannot be converted to Player players.add(name); ? — eric

Think about what that statement means. You have a list of objects with the type Player. You're trying to add name which is a String, not a Player. So the error makes sense. Maybe you should have a look at a basic Java tutorial to get a feel for OOP? — Henry Twist

You need age and sex inputs too player.add(new Player(name, age, sex)); — Mady Daby

You have to get from input all the required data for a new player, create a new player object and add that object to the list. Here you are just trying to add a String to to a List of Player — Rocco

You need to take more inputs as your Player constructor requires String name, int age and boolean sex. Then you can instantiate a new Player object with new Player(name, age, sex) and add a Player object to your list with players.add(new Player(name, age, sex));.

public static void addPlayer(List <Player> players){
    Scanner inputPlayer = new Scanner(System.in);
  
    System.out.print("Enter your player name please : ");
    String name = inputPlayer.next();
    System.out.print("Enter your player age please : ");
    int age = inputPlayer.nextInt();
    System.out.print("Enter your player sex (boolean) please : ");
    boolean sex = inputPlayer.nextBoolean();
    players.add(new Player(name, age, sex));

}

Thank you Mady, change just boolean sex = inputPlayer.nextBoolean();
