Solved Dynamic way to loop through objects.

Hello all,

I'll be short and direct, I want to make a dynamic system for adding Items to my plugin, and
I want to retrieve them by id, but i'm kind of stuck about the correct way.

Example
Imagine I have this 'Main abstract class', called Items

Code:

public abstract class Items{
   //Stuff here
}

Allright, so, imagine I would add three item classes.

Code:

public class Banana extends Items{}
public class Apple extends Items{}
public class Potato extends Items{}

Now, somewhere in the code, I want to get an instance of the super class by a given id.

Code:

public Items getById(int id){
}

Problem
If I would want to do this, I would make a that method in some kind of Manager, and manually add an integer there, and return the instance/object there.

Like for example:

Code:

public Items getById(int id){
   switch(id){
   case 0: return new Potato();
   case 1: return new Apple();
   case 2: return new Banana();
   }
}

I would like this to go in a dynamic way, for when I create a new Items object/instance, that it automatically would be added to this 'switch' (or a list for that matter). I looked into reflection and looping through packages etc, but i'm extremely unfamiliar with that.

Is there a way for this?

Kind regards,

Unica.

Nvm, going for enums.

Solved.
