I have 2 classes, MainActivity and MainGame. If I have a public static void in MainActivity, and one in MainGame. How would I execute the one in MainGame from MainActivity?
For example, I have this:
Main Activity:
public static void 1() { 2(); } Main Game:
public static void 2() { //blah blah blah } 2 isn't a valid method name I think, but if it were you'd just do:
MainActivity.2(); but let's say it isn't and you called it two instead, then maybe you're looking for
public class MainGame { public static void one() { System.out.println("called one()"); } } public class MainActivity { public static void two() { MainGame.one(); } } 
In Java All Names must start with a '_' or alphabet.
So, we can take the method names 1 as _1 and 2 as _2.
The syntax for calling static methods in other classes is ClassName.MethodName(arguments).
So, in this case you would change the code as follows:
class MainActivity{ public static void _1() { MainGame._2(); } } class MainGame{ public static void _2() { //blah blah blah } }
Android, it is general.
