Question

the code I have is:

interfacebase<T>

interfaceA extends interface<A>  ---> interfaceAImpl implements interfaceA 
interfaceB extends interface<B>  ---> interfaceBImpl implements interfaceB


interfaceA  AObj = interfaceAImpl()
interfaceB  BObj = interfaceBImpl()

my question is : can java store AObj and BObj in a List or a Map ?
if java can, then how to achieve that

Answer 1

The following should work, without loosing all type information.

List<interfacebase<?>> list = new ArrayList<interfacebase<?>>();
list.add(AObj);
list.add(BObj);
