Waiting before doing something again

Hi all- I've been developing a bukkit plugin / minigame called "MCHidden" and i've gotten a bit of it done, except i'm trying to add a part which when an arraylist ( called inlobby in my plugin ) reaches a certain number, it tp's everyone in the arraylist to a set location. Any help would be great, because I can't think of how do this. ( I've tried if inlobby.equals(5) but that doesn't seem to work ) Solved > if (inlobby.size() >= 5) {
// teleport players
}
But I want to know how to make it wait before checking again.

 

You need to use this instead

Code:

if (inlobby.size() >= 5) {
// teleport players
}

equals doesn't check the size, it takes an object and checks if it's the same as the array. Not what you want at all.

 

Stevenpcc Thanks i'll try that now. How would you get the plugin to wait before checking again?

bump.
