java - Prevent some class to override the Object class's method in java ，困惑的答案

Question

我在一些网站上发现了这个问题，比如“你会如何阻止某人覆盖 java.lang.Object 类？”但我无法理解任何回应。按照我的想法，它可能完成-

Can create a Base class and all the methods of Object class can be overriden and then we can throw some unsupported exception for each method , so further all subclasses won;t be able to access any of the methods of Object or there is much more better way to do it.

Answer 1

制作一个 FinalObject extends Object 类，该类覆盖每个 Object 方法并使它们成为 final。

class FinalObject extends Object {
  public final int hashCode() { return super.hashCode(); }
  public final int equals(Object o) { return super.equals(o); }
  ...
}
