Append a file

Question

Dear all
i'd like to append the txt content of a file called file2.txt to the end of a file called file1.txt. I used an FileOutputStream with the boolean argument as "true". But in the end, the content of file1.txt is erased/overwritten, just the lines of file2.txt are in file1.txt. Please can you tell me why my code isn't working the way i want?
public void doFile1 (String fileName) throws Exception {
          File file = new File(fileName );
          FileOutputStream fos = new FileOutputStream(file);
          PrintStream p = new PrintStream (fos);
          p.println ("Hi, i'm the first line");
          p.println ("and i'm, the second one, but still from file1.txt!");
          p.flush();
     public void doFile2 (String fileName) throws Exception {
          File file = new File(fileName);
          FileOutputStream fos = new FileOutputStream(file);
          PrintStream p = new PrintStream (fos);
          p.println ("And i'm a line from the second file. HA!");
          p.println ("fajfdsklfdl?sjdskjf?kl file2.txt");
          p.flush();
     //write Vector to file
     public void vectorToFile (String fileName, Vector v)  {
          try {
               Enumeration e;
               File file = new File(fileName);
               FileOutputStream fos = new FileOutputStream(file, true);  //has to be written at the end of file
               PrintStream p = new PrintStream (fos);
               e = v.elements();
               int size = v.size();
               while (e.hasMoreElements()) {
                    String s = (String) e.nextElement();
                    p.println (s);
                    p.flush();
                    //this.headerPrintStream = p;
          catch (FileNotFoundException f) {
               System.out.println ("!!!!!!error in writing temporary header file");
          //return this.headerPrintStream;
     public void appendFiles () throws Exception {
          doFile1 ("file1.txt");
          doFile2 ("file2.txt");
          Vector v = new Vector ();
          v = readFile ("file2.txt");
          vectorToFile ("file1.txt", v);

Answer 1

1) you should call p.close() instead of p.flush()(to
both flush and close the file).
2) these lines:
Vector v = new Vector (); // why allocate a Vector
here...
v = readFile ("file2.txt"); // just to let it be
garbage collected by dropping the reference here
should just simply be:
Vector v = readFile("file2.txt");[bold]

does this ring a bell. Except that assume the l to be
a little bigger in size.Shameful! I'm reporting this as abuse! That poor warnerja was being stalked and 'flipped off' by vincmac!
