This is about recursion and the print out

Question

Please give me a "HINT" on how to;
1- Control the way I print the file out, like instead of printing "A, B, C, D, E, F", printthe alphabets in two lines of three alphabets, like;
"A, B, C"
"D, E, F"
2- A hint on writing a recursion method so I can print out from more than one inFile.
This is what I have so far.import Alphabets;
import java.util.StringTokenizer;
import java.io.*;
public class PrintAlphabets
   public static void main (String[] args) throws IOException
     int n= 100;
      Alphabets[] letters= new Alphabets[n];   //array of numbers
      StringTokenizer tokenizer;
      String line, name;
      String units;     //number of Alphabets available in the file.
          int count = 0;
      String fileout = "c:\\Alpha.txt";
     File file = new File(args[0]);
      FileWriter fw = new FileWriter (fileout);
      BufferedWriter bw = new BufferedWriter (fw);
      PrintWriter outFile = new PrintWriter (bw);
      try
           FileReader fr = new FileReader (file);
           BufferedReader inFile = new BufferedReader (fr);
           line = inFile.readLine();
           while (line != null)
               tokenizer = new StringTokenizer (line);
                 while (tokenizer.hasMoreTokens())
                   try
                      units = tokenizer.nextToken();
                       if ( units.equals("#include") )
                          tokenizer.nextToken();
                       else
                      letters[count++] = new Alphabets (units);
                   catch (Exception e)
                      System.out.println ("Error in input. Line ignored:");
                      System.out.println (line);
             line = inFile.readLine();
         inFile.close();
          for (int scan = 0; scan < count; scan++)
                        outFile.print (letters[scan] + " " );
      catch (FileNotFoundException exception)
         System.out.println ("The file " + file + " was not found.");
      catch (IOException exception)
        System.out.println (exception);
            System.exit(0);
           outFile.close();

Answer 1

I thought I send you te whole code again because I still get the "null" thing.
import Alphabets;
import java.util.StringTokenizer;
import java.io.*;
public class PrintAlphabets
   public static void main (String[] args) throws IOException
     int n= 100;
      Alphabets[] letters= new Alphabets[n]; ;  //array of numbers
      StringTokenizer tokenizer;
      String line, name;
      String units;    
          int count = 0, printCount=0, scan=0;
      String fileout = "c:\\AlphaResult.txt";
     File file = new File(args[0]);
      FileWriter fw = new FileWriter (fileout);
      BufferedWriter bw = new BufferedWriter (fw);
      PrintWriter outFile = new PrintWriter (bw);
      try
           FileReader fr = new FileReader (file);
           BufferedReader inFile = new BufferedReader (fr);
           line = inFile.readLine();
           while (line != null)
               tokenizer = new StringTokenizer (line);
                 while (tokenizer.hasMoreTokens())
                   try
                      units = tokenizer.nextToken();
                       if ( units.equals("#include") )
                          tokenizer.nextToken();
                       else
                      letters[count++] = new Alphabets (units);
                   catch (Exception e)
                      System.out.println ("Error in input. Line ignored:");
                      System.out.println (line);
             line = inFile.readLine();
         inFile.close();
          for (scan = 0; scan < count; scan++)
                        if (printCount == 3)
                           {   outFile.println(); 
                                printCount = 0;
                         String newLine = System.getProperty("line.separator");
                         outFile.print(newLine + letters[scan] + " " );
                        printCount++;
                        //System.out.println(letters[scan] + " "  );
                        //outFile.print (letters[scan] + " " );
      catch (FileNotFoundException exception)
         System.out.println ("The file " + file + " was not found.");
      catch (IOException exception)
        System.out.println (exception);
            System.exit(0);
           outFile.close();
}
