Question

I find the question in some sites like “ow would you prevent someone from overriding the java.lang.Object class?” but none of the response I could understand.
As per my thinking , it may be done –

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

Make a FinalObject extends Object class that overrides each of the Object methods and makes them final.

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