System.out.println（player1.player1HasShield）；从类CharStartingPoint，它打印出true和yes。类CharStartingPoint访问CharObe的变量没有问题。当CharWosna类尝试访问CharObe的变量时，CharWosna可以访问它们，但它们没有初始化，为什么？？？？？要查看此问题，当方法设置npc（）时；调用时，如果player2hassieldbo为true，则player2hassieldbo设置为true。在本例中，player2HasShieldBo设置为false，因为类CharWosna从类CharObe访问了player1HasShieldBo，但是它没有初始化，尽管它在前面已经初始化过。从类CharWosna访问时，字符串播放器1hasshield打印空值。为什么 player1属于CharObe类型，并且具有CharObe构造函数。
player2属于CharWosna类型，并且具有CharWosna的构造函数 这是我的代码，分块讲解 类CharObe: 选择（）；方法：choose方法询问用户是否有防护罩。如果用户对问题键入“否”，您是否有防护罩？布尔Player1Hassieldbo设置为false。如果用户键入yes，则在If语句中输入setPlayerShieldTrue（）；方法被调用 布景播放机现场图（布尔值哈斯菲尔德）；方法：此方法接受布尔值。在该布尔值中，局部变量HasField设置为true，然后分配给player1HasShieldBo returnIfHasShield（）；方法：此方法仅返回布尔player1Hassieldbo 类charstart point，该类调用所有方法 我发现了CharObe的变量被初始化并且可以在这个类中很好地访问的原因，这是因为这个类调用choose（）；方法 接口CharInterface，尚未使用

-从类CharWosna直接访问布尔播放器1hassieldbo
-创建另一个布尔值，使其具有player1hassieldbo的值（当player1hassieldbo等于true时）
-从类CharObe初始化player1hassieldbo（结果并非如所愿，它始终等于true） 如果您想在此处查看我的所有代码，请参阅。 仪表盘

如果（player1Level>=1&&player1Level=1&&player1ShieldLevel首先，您的代码将用于设置布尔值。但是您有一些错误
stackOverflow是由于您在与属性相同的类中创建了CharObe对象而导致的。因此，要创建CharObe对象，需要创建CharObe等等
罪魁祸首：在夏洛贝班上
CharObe f = new CharObe();//remove this
第二件事，你不能仅仅为了读取属性而在CharWosna中创建一个CharObe对象
该代码也是罪魁祸首：
//CharObe object created for acquiring CharObe's variables in that class
CharObe toGet = new CharObe();
在构造函数中创建player2时，尝试传递player1对象
就像在CharWonsa这样：
//CharObe object created for acquiring CharObe's variables in that class
CharObe toGet;
public CharWosna(CharObe obe) {
toGet=obe;
}
最后，在CharStartingPoint类中，创建如下对象：
CharObe player1 = new CharObe();
CharWosna player2 = new CharWosna(player1);
另一个更好的方法是单独维护一个GameContext类，并拥有所有必要的数据，比如玩家，以及从那里访问
不客气。下次请准确回答您的问题。您发布的代码似乎比您的问题合理的代码要多。请阅读并
//CharObe object created for acquiring CharObe's variables in that class
CharObe toGet;
public CharWosna(CharObe obe) {
toGet=obe;
}
CharObe player1 = new CharObe();
CharWosna player2 = new CharWosna(player1);
