Sorry, no.  If you post some code, it will probably be a lot more clear.

(Deep breath.)

Hi, Carramba!

I'm guessing you have two classes something like these (ridiculous
example, I know, but it covers the points):

public class Main {
  public int count = 0;
  public static void main(String[] args) {
     Counter counter = new Counter();
     counter.ChangeThis(count);
     for (int i = 0, n = count; i < n; i++) {
        System.out.println("Args " + i + " = " + args[i]);
     }
  }
}

public class Counter {
  public void changeThis(int count) {
     count = count + 5;
  }
}

This will not work because Java method parameters are pass-by-value,
and no modification of the count variable in the Counter class will
affect the value of the count variable in the Main class.

Here's the solution:

public class Main {
  public int count = 0;
  public static void main(String[] args) {
     Counter counter = new Counter();
     count = counter.getChangedValue(count);
     for (int i = 0, n = count; i < n; i++) {
        System.out.println("Args " + i + " = " + args[i]);
     }
  }
}

public class Counter {
  public int getChangedValue(int count) {
     count = count + 5;
     return count;
  }
}
