Are lambdas always created as SAM types or do they have some other form?

I assume there is some way to specify the SAM type explicitly, for cases where it can't be inferred properly?

The answer to your first question is yes, a lambda is always assigned to a SAM type.

As to your second question, yes, you can cast a lambda to explicitly specify it's target SAM type:

    obj.method((Runnable)(()=> println("oh hai !")));
