title: How to call function every hour? Also, how can I loop this?
body: <p>I need a simple way to call a function every 60 minutes. How can I do this? I'm making a MineCraft bukkit plugin, and this is what I have:</p>
  
  <pre><code>package com.webs.playsoulcraft.plazmotech.java.MineRegen;
  
  import java.util.logging.Logger;
  
  import org.bukkit.Location;
  import org.bukkit.block.Block;
  import org.bukkit.event.block.Action;
  import org.bukkit.event.player.PlayerInteractEvent;
  import org.bukkit.plugin.java.JavaPlugin;
  
  
  public class Main extends JavaPlugin{
  
      public final Logger log = Logger.getLogger("Minecraft");
  
  
      @Override
      public void onEnable() {
          this.log.info("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
          this.log.info("Plaz's Mine Regen is now enabled!");
          this.log.info("Copyright 2012 Plazmotech Co. All rights reserved.");
          this.log.info("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
      }
  
      @Override 
      public void onDisable() {
          this.log.info("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
          this.log.info("Plaz's Mine Regen is now disabled!");
          this.log.info("Copyright 2012 Plazmotech Co. All rights reserved.");
          this.log.info("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
      }
  
      public void onPlayerInteract(PlayerInteractEvent event) {
          final Action action = event.getAction();
          if (action == Action.LEFT_CLICK_BLOCK) {
              Location l1 = event.getClickedBlock().getLocation();
          } else if (action == Action.RIGHT_CLICK_BLOCK) {
              Location l2 = event.getClickedBlock().getLocation();
          }
      }
  }
  </code></pre>
  
  <p>I need to run a function I will implement every hour, how? Remember: The function will use l1, and l2. Also, how can I loop this to get every block inbetween?</p>
