[solved]Command always returning false?

Hi all

I am trying to a simple command to set the time in the world, however the command is always returning false and the time is not changing.

I think the issue is with my args[], but I am not sure what?

Code:

package me.herghost.Fiery.commands;

import org.bukkit.Bukkit;
import org.bukkit.World;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class timeCommand implements CommandExecutor {

	@Override
	public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
    {
        if(cmd.getName().equalsIgnoreCase("settime")&& sender instanceof Player)
        {
        	if(args[0] == "day")
			{
				for (World world : Bukkit.getWorlds())
					{
						world.setTime(0);
					}
				Command.broadcastCommandMessage(sender, "Its is now day time!");
				return true;
			}
			if(args[0] == "night")
			{
				for(World world : Bukkit.getWorlds())
				{
					world.setTime(14);
				}
				Command.broadcastCommandMessage(sender, "Its is now night time!");
				return true;
			}
		}
		return false;
    }
}

Thanks for any help.

Got it!

Code:

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args)
    {
        if(cmd.getName().equalsIgnoreCase("settime")&& sender instanceof Player)
        {
        	if(args[0].equalsIgnoreCase("day"))
			{
				for (World world : Bukkit.getWorlds())
					{
						world.setTime(0);
					}
				Command.broadcastCommandMessage(sender, "Its is now day time!");
				return true;
			}
			if(args[0].equalsIgnoreCase("night"))
			{
				for(World world : Bukkit.getWorlds())
				{
					world.setTime(14);
				}
				Command.broadcastCommandMessage(sender, "Its is now night time!");
				return true;
			}
			else
			{
				Command.broadcastCommandMessage(sender, "Somethings wrong");
			}
		}
		return false;
    }
