Cooldown for command

How can I create a cooldown for a command?
Can you give me an example for the command /kit ?

 

Create a hashmap to store players as keys and java.util.Timer as values. Once the command is called, start the timer for the player and when he calls the command next time, check the time on it. Tell me if you need code examples

 

Ok, Here's my method: It's completely untested, but I think it's a viable method...

Code:java

HashMap<String, Integer> intList = new HashMap<>();
 
if (!intList.containsKey(p.getName())) {
// Add your code here
intList.put(p.getName(), core.getServer().getScheduler().scheduleSyncDelayedTask(plugin, new Runnable() {
@Override
public void run() {
if (p != null) {
intList.remove(p.getName());
}
}
}, 20L)); //20L is the timer on the cooldown
}
 

You'll have to change core. to your own plugin

 

Doesn't work...

I would like some examples...
