Refferencing something in a different class?

Question

hi im new to java and this has pretty much completely halted my progress, this is probably a pretty simple question but if someone could help me out i would really appreciate it
say i have
public class namething
     public String name;
     public namething(String playername)
          name = playername;
}and in another file i create instances of it
public class namepeople
     public static void main (String[] args)
     namething p1 = new namething("bob");
     namething p2 = new namething("alice");
        System.out.println(p1.name);
        System.out.println(p2.name);
}bob and alice will be outputted and all is well, but now if i want to use p1.name or p2.name in a third file, eg:
public class Game
     public static void play(String player1name, String player2name)
        player1name = p1.name
        player2name = p2.name
}then it cant find p1.name or p2.name. what would have to be done for the game class to see these values?

Answer 1

It actually can't find p1 or p2, as those were never defined and initialized in your class.
Game needs a method where you can set p1 and p2. Something like
class Game {
  namething p1;
  namething p2;
  void setNameThings(namething thingA, namething thingB) {
    p1 = thingA;
    p2 = thingB;
}May I by the way suggest that you stick with the Java naming convention for classes, overall chose more descriptive names, and learn a little more about OO design, rather than Java coding?
