How to return the object that holds a class java

I have a class World that holds a class obj开发者_开发百科ect named Player and I would like to be able to inside Player to be able to create an object of the class holding the object. Does what I am saying make sense? Is what im saying possible?

edit:Also Player is abstract and I get an error in the child class when I put some of your code in

You could make a reference named parent, and assign it upon creation. Then, you could use reflection to figure out exactly what that parent's class is.

public class Player{
    private Object parent;
    public Player(Object parent){
        this.parent = parent;
    }
    public Class getParentClass(){
        return parent.getClass();
    }
}

You can just give the world object to the constructor of player

public class World{
  public World(){
    new Player(this);
  }
}
public class Player{
  private World world;
  public Player(World world){
    this.world = world;
  }
}

now you can use the world inside the player with world
