How To Pass A Value Read By A Loop To Main Method

Question

Hey everybody,
I'm at this with my code.I'm reading the values of a text file in a loop.I want to pass these values to main method.The importhant point is I want to do this without using a field. The code is below. Thanks.
//Main
public static void main(String[] args)throws FileNotFoundException
          DoubleClass AvgScore=new DoubleClass();
IntClass Messenger=new IntClass();
          PrintWriter writer1=new PrintWriter("D:\\JavaExercises\\CH07EX14out.txt");
          Scanner scan1=new Scanner(new FileReader("D:\\JavaExercises\\CH07EX14data.txt"));
     //1 ogrencinin notlarini okut ve ortalamasını hesaplat
     while(scan1.hasNext())
          writer1.print(scan1.next()+" ");
calcAvg(AvgScore,scan1,Messenger);
//AvgScore formatlanarak yazdirilacak
writer1.print(""+AvgScore+" ");
writer1.print(""+calcGrade(AvgScore)+"\n");
writer1.close();
//calcAvg
public static void calcAvg(DoubleClass x,Scanner y,IntClass z)
     int counter=0;
     double TotalScore=0;
int NumTests=1;
int Score=0;
//Bir ogrenci icin toplam notu ve test sayisini bul.
     while(counter<=4)
          Score=y.nextInt();
TotalScore+=Score;
counter++;
NumTests++;
//Bir ogrenci icin not ortalamsi bul.
x.setNum(TotalScore/NumTests);
          }

Guys please pay attention,
I already said I can't use a field(class scoped variable)and can't use a return type method.
I ve heard that it can be done by passing a reference or primitive variable to my calcAvg method.And than assignin the read values back to this variable.
But I can't figure out how to make it. I need a complete solution.Including modifications to calcAvg and main method.
Take care,Malkavian187,
Maybe you haven't seen other posters asking homework to be done for them, so here is basically what we tell them: DO IT YOURSELF.
And we realize that very possibly you could fail your class from that and have to drop out. This may be a good thing because it will help keep the demand for technical workers up, and thus, keep the pay high.
On the other hand, if you choose to actually do the assignment then we will be happy to give comments on your code. Please post it when you have some and until then, best wishes with what ever you choose to do.
BTW: the solution you allude to requires a field also... and in reality, you already gave the answer--just implement it. If you do not know how: well, maybe you should do one of the following:
1-read and study the Java Tutorial
2-pay more attention to class
3-read your textbook for your class
4-go to class
5-stay awake in class
6-pay attention in class
7-talk to your teacher
8-withdraw from the class
9-change your major
