[FUN] In-game chat number gen. [1.2.5R1]

Some guy asked me earlier to make a plugin that generated random numbers in the chat, for competition purposes:

So I did, since it was so easy and small I'm just going to release the source code for educational purposes released under the public domain.

Code:

package rollRandom;
 
import java.util.Random;
import java.util.logging.Logger;
 
import org.bukkit.OfflinePlayer;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
 
public class rollRandom extends JavaPlugin
{
public void onEnable()
{
log = this.getLogger();
log.info("Your plugin has been enabled!");
}
Logger log;
public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
{
Player player = null;
if (sender instanceof Player)
{
player = (Player) sender;
}
Random rand = new Random();
        int num = rand.nextInt(101);
        log = this.getLogger();       
sender.sendMessage("Generated Random Number between 0 to 100 is : " + num);     
return false;
}
public void onDisable()
{
log.info("Your plugin has been disabled.");
}
}
