when you declare it static..it can't be changed once assigned. Don't use
static. You're trying to use static so that you can access it from the other
class without having to pass it via a method. You could also use a global
staic class instance..
public class MyGlobals {
static final MyGlbals globals = new MyGlobals();
int someVarINeedToPassAndChange = 0;
private MyGlobals(){}
public static MyGlobals getInstance(){
return globals;
}
}
Then, from any class simply call MyGlobals.getInstance() to access the
shared variables you need.
This is but one way to do it. I am sure there are probably better ways. I
try to pass things via methods when possible.
