Я создаю массив игроков в мини-игре на Java.Существует класс с именем Players и один с именем Game.
. В Main мы сканируем два имени и отправляем их в Game
game.createPlayer(name1, name2);
и позже.попытайтесь получить некоторую информацию обратно
playerArray[(game.getPlayerTurn() % 2)].getPlayerName();
Player создается в Game в виде массива:
public class Game
{
private Player[] playerArray;
[...]
public void createPlayer(String name1, String name2)
{
Player[] playerArray = new Player[2];
playerArray[0] = new Player(name2);
playerArray[1] = new Player(name1);
}
с Playerкак стандартный класс:
public class Player
{
private String playerName;
public Player( String playerName )
{
this.playerName = playerName;
}
public String getPlayerName()
{
return playerName;
}
}
Это, однако, возвращает несколько ошибок, говорящих о том, что он не может найти символ, где бы я ни пытался узнать имя игрока.Разве я не правильно их создал?
Дополнительный код (согласно запросу):
package oop.nimspiel;
import java.util.Scanner;
import java.util.Arrays;
public class Game
{
private int take;
private int turn;
private int playerTake;
private int playerTurn;
protected Player[] playerArray;
public Game(int turn, int playerTurn)
{
this.turn = turn;
this.playerTurn = playerTurn;
}
protected void setPlayerTake(int take)
{
this.playerTake = take;
}
public int getPlayerTake()
{
return playerTake;
}
public void incrementTurns()
{
turn = turn + 1;
playerTurn = playerTurn + 1;
}
public int getTurn()
{
return turn;
}
public int getPlayerTurn()
{
return playerTurn;
}
public void createPlayer(String name1, String name2)
{
this.playerArray = new Player[2];
playerArray[0] = new Player(name2);
playerArray[1] = new Player(name1);
}
public String getPlayer()
{
String playerName = playerArray[(getPlayerTurn() % 2)].getPlayerName();
return playerName;
}
public void checkTake(int take)
{
Scanner input = new Scanner(System.in);
this.take = take;
boolean rightInput = false;
do {
if (take < 1 || take > 3)
{
System.out.println("Your input was wrong, please use a number between 1 and 3.");
System.out.println("How many stones would you like to take?");
