Question

I have a class Player which I load from a database:

public class Player{

    int id, score;
    String name;

    public Player(int id, String name, int score) {
        this.id = id;
        this.name = name;
        this.score = score
    }

    public int getID() {
        return id;
    }

    public String getName() {
        return name;
    }
    public String getScore() {
        return score;
    }
}

The class Main has all of them in an ArrayList<Player> player.

Is it possible to find a particular instance of that class with something similar to the where clause in SQL?
I just need the name if I have the ID.
Example:

"SELECT name FROM Player WHERE id = 5";

Answer 1

No, but you can keep your Players in a HashMap:

HashMap<Integer,Player> players;

and then get the required Player with:

Player player = players.get(5);
