        System.out.println("What player would you like to look up?");
        int choice = Integer.parseInt(EventHandler.keyboard.next()); choice -= 1;
        System.out.println(Players.player[choice].name);


    }

}

球员类

public class Players extends EventHandler {

    public static int playerAmount;
    public static Player[] player;

    public static void setPlayers(){    
        player = new Player[playerAmount];

        for(int i = 0; i < …
