Font BOLD in doc files.

Question

Hi Guys,
I have used a Random Access File to create a file and I am writing some data within the file.
How do I change the contents of the file so that I can use different fonts for the data.
Shall I change the font at the time of writing(If yes ,how..) or after making the file(If yes ,how..).My code is given below:
try{
               DataOutputStream addressfile = new DataOutputStream(new FileOutputStream(new File (TEMP.get("filename").toString()+".doc")));                                   
               List answers = (ArrayList)TEMP.get("answer_options");
               List count_options = (ArrayList)TEMP.get("count_options");
               List count_options_percent = (ArrayList)TEMP.get("count_options_percent");
     int size = count_options_percent.size();
     long filelength;
     int j = 1;
     addressfile.writeBytes("\n\n\n");
     addressfile.writeBytes("VOTE OPTIONS");           
     addressfile.writeBytes("\t\t");
     addressfile.writeBytes("NUMBER OF PEOPLE");           
     addressfile.writeBytes("\t\t");
     addressfile.writeBytes("PERCENTAGE");
     for(int i = 0;i<size;i++){
          addressfile.writeBytes("\n");
          addressfile.writeBytes(j+")");
          addressfile.writeBytes(answers.get(i)+"");
          int numberspaces = 28-answers.get(i).toString().length();
          for(int k=0;k<numberspaces;k++)           
               addressfile.writeBytes(" ");
          addressfile.writeBytes(count_options.get(i)+"");
          int numberspaces2 = 21 - count_options.get(i).toString().length();           
          for(int k=0;k<numberspaces2;k++)           
               addressfile.writeBytes(" ");
          addressfile.writeBytes(count_options_percent.get(i)+"");
          addressfile.writeBytes("\n");
          j++;
     addressfile.close();
          }catch(Exception e){
               logger().error("Writing to a file error");
               throw new NoSuchFieldError("Writing to a file error");
Thanks in advance for your suggestions:
Yours sincerely,

You've clearly been reading this thread and responding to it, but also it's pretty clear that none of what's been written above has actually sunk in.
Short of decoding the MS proprietary doc encoding scheme, or using an external API, you cannot generate .doc encoding the way you are trying to do it.
I do not know (nor do I ever intend to know) the MS encoding schemes for their proprietary document types. If my clients require functionality I inform them that they need support libraries, if they don't want that they do not get the functionality.
