Java 是什么导致我的代码冻结？我没有主意了

我正在用Java开发一个游戏引擎，我还在努力学习如何正确地制作GUI。我的代码的工作方式（或者，至少，我希望它如何工作）是我有一个名为Main的类和一个名为BattleFrame的类。BattleFrame有一种方法，可以将系统输出重置为其中的文本字段。BattleFrame包含GUI，而Main控制按下按钮时发生的事情以及游戏中的事件顺序。在main中，有一种方法可以根据先前保存的数据（存储在文本文件中）加载游戏世界。当main启动时，它调用BattleFrame，它以只有一个按钮的形式加载，continue（稍后我将添加新游戏）。当用户按continue时，actionPerformed将转到Main，然后它将打印“Hello”。然后它对按下的按钮是continue这一事实做出反应，并加载世界。这就是问题发生的地方，因为当我删除它时，“Hello”会被打印到文本字段中，但当该方法存在时，gui会冻结

通过调试，我发现所有冻结的方法都是Load类中类Player的初始化。在我调用player=newplayer（name）（该名称是先前从文本文件读取的，并且是正确的）之后，调试器本身停止。在这一点上，我不知道为什么会发生这种情况。加载播放器之前是有效的，直到我开始处理主类，在我开始处理gui之前，所以我怀疑问题一定在哪里，但我真的不知道。提前为我的丑陋代码感到抱歉，我知道我在写一些可以理解的东西方面还有很多需要学习的地方

public class Main {

    static World world;
    static Player player;
    static Clerks c;

    static BattleFrame bf;
    static InputCheckers i;
    static Species species;
    static Load l;
    static Specie bear;
    static Shop sh;

    static Save s;
    static Battle b;

    public static void main(String[] args) throws IOException, UnsupportedLookAndFeelException, InterruptedException 
    {

        c = new Clerks();

        species = new Species();

        bear = species.getBasicBear();
        sh = new Shop(c.getFirstClerk());

        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    bf = new BattleFrame();
                    JTextAreaOutputStream out = new JTextAreaOutputStream(bf.textOut);
                    System.setOut(new PrintStream(out));
                    bf.setVisible(true);
                } 
                catch (InterruptedException ex) 
                {
                    Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
                }

            }
        });
   }

    public void perform(JButton e) throws IOException 
       {
           System.out.println("Po");
           String button = e.getName();
           if(button.equals("continue"))
           {

               newGameOrContinue("c");
           }
           else if(button.equals("new game"))
           {
               System.out.println("    ");
               newGameOrContinue("n");
           }
       }

    public static void newGameOrContinue(String nOrC) throws IOException 
    {

        System.out.println("Hello");
        if (nOrC.equals("c")) {
            Load l = new Load();

            try{
            world = l.loadWorld();
            }
            catch(IOException a)
            {
                System.out.println("WTF");
            }
   }

我现在想要的是代码不要冻结，应该打印出来的文本要打印出来。再一次，为这混乱的代码道歉，相信我，我已经尽力了。如果代码在这里，我试着只放必要的部分，如果格式错误，我会修改它，这是我第一次在这里提问。提前谢谢

函数

nameSetter（）

在

Player

应用构造函数之前被调用，而静态函数

nameSetter（）

需要用户输入，这是您在

BattleWindow

中禁用的，因此程序将等待永远不会发生的用户输入。只需将

Player

构造函数更改为以下内容：

public class Player extends GameObject {

  protected static Equipment equipped = new Equipment();
  protected static Species species = new Species();
  protected Specie human = species.getBasicHuman();
  protected int maxHealth;
  protected int speed;
  protected int str;
  protected Double luck;
  protected int def;
  protected int currentHealth;
  protected int wealth;

  Inventory inv = new Inventory();

  public Player() {
    super(Player.nameSetter(), "Player Controlled", System.getProperty("user.dir") + "src\\main\\java\\cz\\com\\GameFiles\\LevyBuild\\Sprites\\Objects\\Items\\Misc\\BearClaw.png");
    properties();
  }
}

---

请注意，无论何时创建

Player

的新实例，它都会再次崩溃。您需要再次启用用户输入。

如果您的父类被称为

对象

，那么这是非常糟糕的做法，这取决于您在那里使用参数做什么，否则-如果没有任何参数-代码应该失败，因为只有默认构造函数没有参数-

对象（字符串a，字符串b）

在给定代码中不存在代码是否编译？如果是这样，那么在

属性

方法中阅读的

人类

是什么？请了解java命名约定。所有类名都应该大写。是的：不要在自己的类中重复使用对象等名称。长话短说：请确保遵循。使用链接改进您的问题（不要通过评论添加更多信息）。否则我们将无法回答您的问题并帮助您。@xxxvodnikxxx不，我添加了点以显示该类有更多的代码，但我认为这与我的问题无关。我的代码已经足够长了。你说得对，我将把类对象重命名为类似“Generic”的东西。它的要点是，我不必为每个新游戏对象定义名称和精灵位置（不是代码，我真的应该选择一个更好的名称）。那么您认为简单地更改（并折射）类名就可以解决问题吗？谢谢你的回复！
