Reading char fail

Question

Hi everybody!
Reading one char at a time from a file and saves where i last read.
Next time when i start reading chars from where i last read in the file i
only get char "?", and it reads chars like that the entire time. Any advice ?
br.skip(last_read_in_file);
while(readed_char != '\n'){
     if((int)(readed_char = (char) br.read()) != -1){
          if(readed_char != '\n'){
               line_x = readed_line;
               readed_line = new char[readed_line.length + 1];
               for(int i=0;i<line_x.length;++i)
                    readed_line[i] = line_x;
               readed_line[readed_line.length - 1] = readed_char;
     if(read_no_of_chars >= size_of_file){
          readed_char = '\n';
     System.out.println("readed_char: " + readed_char);
     ++read_no_of_chars;

Answer 1

The FIRST time i read the file there is no problem when i'm reading chars.
The SECOND time it returns "?" or 65535. There has to be something with skip(long n) ?
fx = new File("C:\\Temp\\Log.txt");
// Get the size of the file.
noOfChars = (int)fx.length();
// If last_read_in_file is smaller then the size of
// of the file, it means that new errors
// has been added to the file. Otherwise,
// jump out of this error-detecting function.
if (last_read_in_file >= noOfChars) {
     logger.info(fx.getName() + " - done, no changes in file.");
     return;
// Initiate file-readers.
in = new FileInputStream(fx);
fr = new InputStreamReader(in, charset);
br = new BufferedReader(fr);
// Jump to the latest read line.
read_no_of_chars = last_read_in_file;
try {
     in.skip(last_read_in_file);
     fr.skip(last_read_in_file);
     br.skip(last_read_in_file);
} catch (IOException e1) {
     e1.printStackTrace();
// Reading a line from the file which, perhaps,
// contains errors. In this while-loop a char is
// being read one at the time and is being added
// in a char-array. Thanks to the CharSet, when
// we're at the end of the file, it won't
// return the value -1. So instead, we have a
// word-counter that we compare with 'noOfChars'
// to see if we're at the end of the file.
while(readed_char != '\n'){
     if((int)(readed_char = (char) br.read()) != -1){
          if(readed_char != '\n'){
               line_x = readed_line;
               readed_line = new char[readed_line.length + 1];
               for(int i=0;i<line_x.length;++i)
                    readed_line[i] = line_x;
               readed_line[readed_line.length - 1] = readed_char;
     if(read_no_of_chars >= noOfChars){
          readed_char = '\n';
     System.out.println("readed_char: " + readed_char + " (" + (int)readed_char + ")");
     ++read_no_of_chars;
temp = new String(readed_line);
