Is there anyway this program can work the way I want it to work!!??

Question

Since I had no idea, how to make a new line in .txt in my program(writeBytes("\n") will just make a rectangle in the .txt file)..i decided that I should make a method..below:
public static String makeLine(int bytesReq)
          String lines = " ";
          //bytesReq /= bytesReq;
          for(int i = 0; i < bytesReq; i++)
               lines += lines;
          return lines;
     }I wanted program to create a string of empty spaces..depending on the number so I can use it later...in this code..which transfers the stuff inside my link list into the .txt file...
     public static void loopList()throws IOException
          try
               RandomAccessFile rand = new RandomAccessFile(filet, "rw");
               EmpLink current;
               current = first;
               if(first==null)
                    delay(options.geTime());
                    System.out.println("List is empty!");
               else
                    //rand.seek(filet.length());
                    while(current != null)
                         for(int i = 0; i < options.getLoops(); i++)
                              rand.seek(filet.length());
                             rand.writeBytes("ID: "+current.emp_id + " Name: " + current.fname + " Surname: " + current.lname+" ");
                              rand.seek(filet.length());
                              rand.writeChars(makeLine((int)filet.length()/2));
                         current = current.next;
                    delay(options.geTime());
                    System.out.println("TRANSFER COMPLETE!!");
                    System.out.println();
          catch(Exception enk)
               System.out.println("");
               System.out.println("There has been a fatal error during execution!!");
               System.out.println("");
     }when I compile it seem to work but when I run it...it has a OutOfMemoryException..and I don't know why..later I used the length of the string of the ID, Firstname, Lastname but then...something weird happens....
all of them is repeated three times in .txt and I have no clue why?..
And right now the .txt file has some kind of east asian characters written in it and is 513KB and still don't have a clue why...
all I want is to have the next set of data go into the next line....
Please help...

This returns a string 2^bytesReq long because it doubles in length on every pass.
