Given a plane $\alpha$ and two non-coincident straight lines $m$ and $n$, consider the following four propositions:
(1) If $m \parallel \alpha$ and $n \subseteq \alpha$, then $m \parallel n$.
(2) If $m \parallel \alpha$ and $n \parallel \alpha$, then $m \parallel n$.
(3) If $m \parallel n$ and $n \subseteq \alpha$, then $m \parallel \alpha$.
(4) If $m \parallel n$ and $m \parallel \alpha$, then $n \parallel \alpha$ or $n \subseteq \alpha$.
Identify which of the above propositions are correct (write the number).
