Javascript 如何修复不可访问的方法

当我创建类

champosion

的对象时，它显示没有可访问的方法

对于（int lap=1；lapYes），除了
champion
对象的默认构造函数之外，所有方法都标记为私有，因此只能在类实现本身内部访问

只要实例化
champosion
对象的实例，就会自动调用
startgame（）
方法

public static void main(String[] args) {
  Championship sim = new Championship();
  sim.startgame();
}

如果您希望能够在不立即调用
startgame（）
方法的情况下创建
champion
实例，或在实例化外部调用
startgame（）
方法，请标记
startgame（）
public
和/或从构造函数中删除
sim.startgame（）

方法原型应该匹配

public void startgame() {
  ...
}

“没有可访问的方法”是什么意思？你在构造函数中调用
sim.startgame（）
，你说它编译得很好。我也很困惑，这个错误消息出现在哪里，它到底是什么？“javascript”？？这不是javascript，而是java。我的意思是，当我创建一个类冠军的对象，然后右键单击该对象尝试访问任何方法时，它表明没有可访问的方法。
