After t.start() is called, r's run method can be executed at the platform's discretion. It's unlikely that run will be invoked immediately after the start call (prior to the next line in the current thread), but it's possible.

No lines are "skipped." After 'r' is given a chance to run, the main thread will resume where it left off.

IMPORTANT EXAM TIP: Note that sleep is a static method in Thread. It puts the current thread to sleep, even if called through some other Thread instance. For example, in this code, when you call t.sleep, you are not putting t to sleep -- you are just calling Thread.sleep by way of t.
