Naming methods to generic arguments

I am going over some code and I am adding some interfaces so i can make sure all the classes follow the same basic guidelines.
Now I have an interface called Uni < T > which takes exactly one generic argument.
Say I have a class which implements Uni< Foo > then I would like that class to have this method public foo getFoo(){};
Is there any way to add this method to the interface? I would prefer if i could do something like this in my interface public T getT(); and the second T gets replaced by the generic argument.

I can't just call it "get" because I would like some classes to implement multiple versions of Uni. public Example implements Uni<Foo1>,Uni<Foo2>

I know I can give the function 'get' an argument Foo or Class but I'd rather not so I thought I'd ask here. (I would also mess up the naming convection if i did this)

its not possible with java but you can do it like this

public interface example<T> {
   public void yourmethod(T object);
}

make the interface according to the generic type you want.

No, not possible. And as generics in Java are implemented via erasure (i.e. dropped by the compiler), you will also not be able to implement multiple versions in a single class.
