Solved Weird stuff happening with BukkitRunnables pls help

Ok, I am posting another thread, it is just because BukkitRunnables stopped working. I am making a plugin that detects every second if your Y coordinate is under something like 30 or so. Now I made a sepereate class (not extending BukkitRunnable) and when I do

Code:

new BukkitRunnable {
        @Override
         public void run() {
           //methods
        }
    } 

It doesn't work. The code turn all red and stuff. Now I basically copied and pasted code from a previous class and pasted it in another class (they did not implement anything and I am confused why is this happening).
The code was the same, I just deleted the other class coz the name had a typo in it and I do not like seeing typos.
Pls help

 

Code:

package com.xpaintall.TutorialMain.BridgeChallenge;

import com.xpaintall.TutorialMain.TutMain;
import org.bukkit.Bukkit;
import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerEvent;
import org.bukkit.scheduler.BukkitRunnable;

public class detectingylevel implements Listener {



    TutMain plugin;
     detectingylevel(TutMain plugin) {
         this.plugin = plugin;
     }

         new BukkitRunnable() {
             @Override
             public void run() {
                 Bukkit.broadcastMessage("something");
             }


         }.runTaskTimer(plugin, 0, 1*20);

}
