Help with making commands

Commands won't work, and having trouble with arguments.

Code:

package me.FusionTech.FisionPlugin;
 
import java.util.logging.Logger;
 
import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.Event;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;
 
@SuppressWarnings("unused")
public class Fision extends JavaPlugin {
    public final Logger logger = Logger.getLogger("Minecraft");
    public static Fision plugin;
 
    @Override
    public void onDisable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName()
                + "[FissionPlugin] Has been Disabled");
 
    }
 
    @Override
    public void onEnable() {
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() + " Version " + pdfFile.getVersion()
                + "[FissionPlugin] Has been Enabled");
        getConfig().options().copyDefaults(true);
        saveConfig();
 
    }
 
    public boolean onCommand(CommandSender sender, Command cmd,
            String commandLabel, String args) {
        Player player = (Player) sender;
        if (commandLabel.equalsIgnoreCase("staff")) {
            player.sendMessage(getConfig().getString("Staff"));
        }
        if (player.hasPermission("fission.heal.ulti")) {
            if (commandLabel.equalsIgnoreCase("Ultiheal")) {
                player.setHealth(20);
                player.setFoodLevel(20);
                player.setRemainingAir(20);
                player.setFireTicks(0);
                player.sendMessage(ChatColor.DARK_GREEN + "You have been healed!");
            }
        if (player.hasPermission("fission.list.staff")) {
            if (commandLabel.equalsIgnoreCase("speed")) {
                player.setWalkSpeed(9);
                player.sendMessage(ChatColor.DARK_GREEN + "Walk speed set to 9");
               
                }
            }
        if (player.hasPermission("fission.away")) {
            if (commandLabel.equalsIgnoreCase("away")) {
                if (args.length() == 0) {
                    player.sendMessage("Too little arguments");
                if (args.length() == 1) {
                    Player targetPlayer = player.getServer().getPlayer(args[1]);
                    Location location = Location(getConfig().getString("Away Location"));
                }
                }
            }
           
        }
        }
        return false;
    }
 
    private Location Location(String string) {
        // TODO Auto-generated method stub
        return null;
    }
}

 

You don't mean String args, you mean String[] args
