# Global Fields You can make field declarations outside of a class. This makes these fields "global" to the program. We call things global when they are available at every point in the "world" of our program.[^wonthold] ```java int number = 0; void main() { IO.println(number); number++; IO.println(number); } ``` [^wonthold]: This explanation is I think a correct description of what it means to be global, but what I am showing won't really hold up as a global thing the more you learn.
