Is there any method to extract code out of the class?

I`m doing wrong

Code:

public class MainActivity extends JavaPlugin implements Listener{
    private Extras extras=new Extras();
 
    @Override
    public void onEnable() {
        extras.echo("Hello");
    }
}

Code:

public class Extras extends JavaPlugin  {
    public void echo(Object obj) {
        getLogger().info(String.valueOf(obj));
    }
}

Got a message that says:

 

@timtower

thats the question, if i don't extend java plugin i can't acces to getlogger from Extras

echo works great if is in the MainActivity class

 

Another option is to pass an instance of the main class to the classes that need it. i.e.

Code:

public class MyClassName extends JavaPlugin {
  public void onEnable() {
    getServer().getPluginManager().registerEvents(new EventClass(this), this);
    getCommand("somecommand").setExecutor(new CommandClass(this));
  }

public class EventClass implements Listener {
  MyClassName plugin;

  public EventClass(MyClassName plugin) {
    this.plugin = plugin;
  }

 

@Strahan I feel fool after your answer, I was making the easy dificult

@timtower I am sorry to tell you that I did not understand you, for now...

Thanks...
