List online players as an int?

I'm wanting to show in my login/logout messages the number of players that are currently online, but not their names. I know there is getOnlinePlayers() for the Server class, but it returns a string. How do I output online users as an integer?

Nevermind, I'm a dunce. Solved it with Bukkit.getOnlinePlayers().length.
