I need to defined a Generic type as a subclass implementing an interface, like this (DOES NOT COMPILE):
public class Foo<T extends SomeClass implements SomeInterface> {
...
}
Is it possible to do something like this?

These are called Intersection Types. They don’t differentiate between classes and interfaces. Intersection types are also briefly mentioned in the Java tutorial on Bounded Type Parameters.
