How to separate my plugin into multiple classes

Question

I use java and paper plugin. I made this myself, but it doesn't work well.

source code

package com;

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


public class [[mainclassname]] extends JavaPlugin implements Listener {

    public void onEnable() {
        getLogger().warning("Server started.");

        testing test = new testing(); // An error occurred that starts from here.
        test.onEnable();

        getLogger().info("Nice try!"); // check point
    }
}


class testing extends JavaPlugin {
    public void onEnable() {
        getLogger().warning("Hello!");
    }
}

build successful.

error : Error occurred while enabling [pluginname] (Is it up to date?) java.lang.IllegalArgumentException: Plugin already initialized!

It's not possible. Why do you want to do it ? – Elikill58 Feb 20 '22 at 13:01 — Elikill58, Feb 20 '22 at 13:01

The PluginAlreadyInitialized error occours when the .jar file contains more than one subclass of JavaPlugin class.

From here.

I cannot understand, could you let me know more details? – nooob Feb 20 '22 at 10:08
@nooob You cannot define two JavaPlugin on the same project or package and you are defining two. – dcolazin Feb 20 '22 at 11:40
Oh I found it already sorry }; – nooob Feb 20 '22 at 11:47
@nooob And you got the same error? – dcolazin Feb 20 '22 at 11:55
No, but I couldn't have found how to fix. – nooob Feb 21 '22 at 08:52
@nooob then you have to open a new question – dcolazin Feb 21 '22 at 09:10
