It possible to hide a property of superclass?

[D. Formenton]

Hi,

If I extends a class A to Class B, in B I can see all public getters and setters (and public methods).

My question is: it possible to avoid to show some (not all) of public getters and setter (and public methods) of superclass when I use the subclass?

Thank you

Of course, this is not recommended, as a subclass IS-A superclass, and must work in place of a superclass. However, if you really want to do this, one option could be to "disable" the public methods by overriding them -- to throw an exception. The overridden method is still accessable to the subclass, as it can use the super keyword.

What Henry said. However, it is possible to hide/remove methods by wrapping rather than subclassing, particularly if the "superclass" implements an interface.
