The constructor Commands() is undefined - Java / SpigotMC

Question

I know there are other questions like this but none that I could find are fully helpful to this case.

So basically on the line that says

getCommand("minealchemy").setExecutor(new Commands());

I get this error:

The constructor Commands() is undefined

Any help? When i put "null" in the () for Commands ... Commands(null)... then i get a NullPointerException error...

Here are all of my classes:

Main Class:

package me.zachbears27;

import org.bukkit.event.Listener;
import org.bukkit.plugin.java.JavaPlugin;

import me.zachbears27.utils.Commands;

public class Main extends JavaPlugin implements Listener {

    @Override
    public void onDisable() {
    }

    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(this, this);
        registerConfig();

        getCommand("minealchemy").setExecutor(new Commands());
    }

    public void registerConfig() {
        saveDefaultConfig();
    }

}

            Player p = (Player) sender;

            if (cmd.equalsIgnoreCase("minealchemy")) {
                if(args.length > 0) {

Change the .setExecutor(new Commands()) in the onEnable() function to

.setExecutor(new Commands(new Methods(this)))
