cast at call site problem (original) (raw)

The call foo(Collections.emptySet()); is much more clean I suppose. I just wonder why the redundant cast leads to compilation error.

Thanks

I believe you want to write this: foo(Collections.emptySet());

Hello all,

Is it a bug or is it an intentional behavior: This code compiles {code} void foo(Set s) {}

void bar() {
    foo(Collections.emptySet());
}

{code}

but this code doesn't: {code} void foo(Set s) {}

void bar() {
    foo((Set<String>)Collections.emptySet());
}

{code}

Lambda build 83.

Thanks Anna
