java - How can I use protected variables to good effect in abstract classes? -

i suppose i'm asking best practice is. take example:

public abstract class gameobject {  protected vector2 position;      protected gameobject(vector2 position) {         this.position = position;     }      protected vector2 getposition() {         ...     }      protected void setposition(vector2 position) {         ...      } ... } 

if have gameobject abstract class player extends, should setting of fields (e.g. speed, position) , methods in gameobject protected?

what's nice way of doing this?

in order comply data encapsulation, practice keep fields private/protected , methods public.
