从重写Java方法中禁止子类 [英] Disallow subclasses from overriding Java method

问题描述

假设我在Java类中有一个方法，我不希望该类的任何子类能够覆盖该方法。

Suppose I have a method in a Java class, and I don't want any subclass of that class to be able to override that method. Can I do that?

推荐答案

您可以将方法声明为 final ，如：

You can declare the method to be final, as in:

public final String getId() {
   ...
}
