Interface
Hi, i've this interface but there is only 1 class which doesn't need any parameter in
getAll(long id) method. I'd like to implement the interface on the class MaterialManager but is there a way to specify/override the getAll() method without any parameter ?

You can just implement the GetAll method from the interface with the parameter but call your parameterless method inside it.
ok then i will do that , i was asking in case there is a solution
thanks
Generally if you find yourself in the situation of 'because my class implements this interface it has to implement some method it doesn't need', it's a sign that your interface is too big
instead of having one
IManager interface, have smaller interfaces that compose up to create IManager
then your class can only implement the interfaces it actually needs
that said, Thinker's answer is good in this situationNot implementing some methods in the interface/base class is part of many design patterns anyways, mainly in the component tree one or whatever
