the first 3 numbers are the coordinates, the second three are the rgb values.
Right now i'm using this code to read them in:
   try
      {
         d = new DataInputStream( new BufferedInputStream(
                            new FileInputStream(ptsFile) ) );
      }
      catch ( FileNotFoundException ie)
      {
         return -1;
      }

      try
      {
         while ((d != null) && (d.available() > 0))
         {
            s = d.readLine();/*StringOperations.nextData(d);*/
            if (s != null)
            {
               tokens = new StringTokenizer(s);
               if (tokens.countTokens() == 6)
               { //Parse tokens as normally

any suggestions, coz i need to read in a million of these points:)

okay i figured out i need to use Nio;)

but right now i have it like this, first i put a integer in a bytebuffer, this is the total number of points to be read in, after that i put the coordinates array in it. and finally tthe rgb values. 
Then i want  to create directly floatbuffers from it by its given position and limit, but how can i do this:)

what i want( don't know if it's possible is the following ):
at position 4 ( coz of the first integer in the buffer) my vertex positions starts with goes from 4 till (sizeOf(float)*4*numPoints),
and then i want to read in the byte values that are stored after the vertices. I don't want to use getFloat() coz i want to give the buffers directly to opengl
but is it posible, coz i read the the method asFloatBuffer for instance read from 'position' to the end of the buffer
