quick java question

So I'm making a program for the lulz, and I've realized something. Almost all of my classes need to access the same coordinates, x and y, and half of them need to alter x and y. So, I have the coordinates as public ints. But it's going to be a pain to have to type locationList[4][5].x every time I want to alter or use x.

Isn't there a way I could use x and y as if they were a natural part of every class? How would I do that?

Yes. Create a java file called Global, or something like that, then include it in every class that needs it. From there you can access and manipulate them directly.

Code:

---

//global
int x, y;

---

Code:

---

//Some class
#import "global"; //I don't remember the exact syntax for this.

int somevalue = global::x;

Been a while since I've used java, so the syntax might be a little off, but that's how to do it. :)

It's been a while since I've used Java as well, but if I understand your question correctly, you can simply declare x and y as global variables. This is accomplished by declaring them outside of all of your methods.

E.g.,

Code:

---

public class programForLulz{

  int x, y;

  public static void main etc...

Those would be global to the class, not between classes :P

Ah yeah. :|

You could have a superclass with those variables that all your classes extend.

Or you could make them static variables, if you only need one set of those variables.

Yeah, superclass... I think that's what I need. (Syntax?)

This is where my intro class never finished. We started interfaces, but then the professor was all "Wait. That's not going to be on the exam. Let's talk more about exceptions instead."

I don't think you understand the concept of inheritance :P You don't need to inherit anything, just needs to be included.
