java - 需要 Player 类中的玩家对象

Question

在 initPlayerOnJoin 中，我需要访问玩家的余额。这很可能是一个简单的修复，但我仍在学习 OOP 的概念。

 public class Player {

private String name;
private Stock stock;
private Integer balance;


  public Player(String name) {

    this.setName(name);

    initPlayerOnJoin(this);
  }

  private static void initPlayerOnJoin(Player player) {
    player.addBalance(500);
  }
  public void addBalance(Integer amount) {
    balance += amount;
  }
}

Answer 1

 public class Player {

private String name;
private Stock stock;
private Integer balance;


  public Player(String name) {

    this.setName(name);

    initPlayerOnJoin(this);
  }

//To get the balance
  public Integer getBalance() { return balance; }

  private static void initPlayerOnJoin(Player player) {
    player.addBalance(500);
  }
  public void addBalance(Integer amount) {
    balance += amount;
  }
}
