Solved How to "connect" two class ?

Hello , i want to ask you , how to "connect" two classes. More in the photos . Thank you

 

only main class should extend JavaPlugin. registerevent for Listener class only so it is not proper way. it seems your axe class is a command and should implement CommandExecutor. Then you may getCommand then setExecutor an instance of your axe class.

 

What you are doing wrong:
1. You are using the method registerEvents() but in the Axe class you are defining a command. Use:

Code:java

getCommand("YOUR COMMAND").setExecutor(new Axe());

2. Your class Axe must implement the interface CommandExecutor. Also, only the main class can extend the class JavaPlugin. Correct:

Code:java

 public class Axe implements CommandExecutor { 

 

Like this I believe

Code:java

package //package here
import //imports here
public class MyPlugin extends JavaPlugin {
    //declare the inventory object
    public static Inventory inventory = Bukkit.createInventory(null, 18, "Guns");
    //whatever methods you use will go here
    //whenever you call your other class, do this:
    MyOtherClass myOtherClass = new MyOtherClass(this);
    //"this" is a reference to your main class
    //you will be passing this instance of the main class to your other class
}

 

Thank you guys @seasonguy , @Max8801 , @YoloSanta .

 

With this you will need a constructor in the class MyOtherClass. Add one in like that:

Code:java

 
private MyPlugin plugin;
public MyOtherClass(MyPlugin plugin){
     this.plugin = plugin
}
 

From there on, you will be able to use the field plugin to access the class MyPlugin
