[rules-users] Simple Global Error !!

[Esteban Aliverti]

Let's say you have this method in a java class:

public void addOne(int number){
   number = number +1;
}


And let's say you want to invoke that method from another method in the
same (or a different. It doesn't matter) object:

int number = 0;
this.addOne(number);
System.out.println("Number= "+number);

What is the output of the code above? Figure out that and you will figure
out what is happening with your global.

Best Regards,
