Re: Problem reading random access file

<http://www.physci.org/codes/sscce.jsp>
The following SSCCE produces this output:

6
0
2
the first byte read is: 6
3
6
The read error is: java.io.EOFException

Using this sscce, could you initialize byte[] ba
with your desired data, run it, and post the results?

public class finalTest
{
  public static void main(String[] args)
  {
    File f = new File("Class Room Details.rsh");
    try
    {
      BufferedOutputStream bos =
        new BufferedOutputStream(new FileOutputStream(f));
      byte[] ba = new byte[]{4,5,6,4,5,6};
      bos.write(ba);
      bos.close();
    }
    catch (FileNotFoundException e)
    {
      e.printStackTrace();
    }
    catch (IOException e)
    {
      e.printStackTrace();
    }

    readData();

  }

  public static void readData()
  {
    int by = 2;
    try
    {
      File f = new File("Class Room Details.rsh");
      RandomAccessFile raf = new RandomAccessFile(f, "r");
      System.out.println(raf.length());
      System.out.println(raf.getFilePointer());
      raf.skipBytes(by);
      System.out.println(raf.getFilePointer());
      System.out.println("the first byte read is: " + raf.readByte());
      System.out.println(raf.getFilePointer());
      raf.skipBytes(by = 4);
      System.out.println(raf.getFilePointer());
      System.out.println("the second byte read is: " + raf.readByte());
      System.out.println(raf.getFilePointer());
      System.out.println(raf.length() - raf.getFilePointer());
    }
    catch (IOException r)
    {
      System.err.println("The read error is: " + r.toString());
    }
  }
}
