假设我上了课，我不希望任何人在

扩展课程中覆盖一个方法;我可以让这个方法最终。假设我不希望任何人从我的课堂上扩展他们的班级。我可以让整个班级最终完成。


亲切的问候，

Suppose I''ve made a class and I don''t want anyone to override a method in an
extending class; I can make that method final. Suppose I don''t want anyone to
extend their class from my class; I can make that entire class final.

kind regards,

在java中他们说过教程网站：

"从构造函数调用的方法通常应该被声明为final。如果构造函数调用非final方法，则子类可能会以令人惊讶或不合需要的结果重新定义该方法。

为什么从constractors调用的方法？

in the java tutorial site they stated:
"Methods called from constructors should generally be declared final. If a constructor calls a non-final method, a subclass may redefine that method with surprising or undesirable results."
why methods called from constractors??
