file output garbeled!

[bobo12]

hi, i am quite puzzled, the following trivial code prints 0 to file. any suggestions!

try {
BufferedWriter out = new BufferedWriter(new FileWriter(outputfile));
out.write("ITRS SYSTEM");
out.newLine();
out.write(" (ITRS) ");
out.newLine();
out.write(" TEST SUBSYSTEM ");
out.newLine();
out.flush();
out.close();
} catch (IOException e) {
System.out.println("excpetion caught" + e);
System.exit(1);
}

The code works fine, assuming the File object "outputfile" is valid. I used:

File outputfile = new File("testfile.txt");

I suspect something about your File object is incorrect.

ok a few more clues...
when using DataOutputStream out, out.write(...) throws an EOFexception. why is that?
i thought i simply writes to file and moves the EOF accordingly. this is very strange, a write func should move the EOF marker right?

also, after a few out.write's, when i do out.size(), nothing is printed, why is that?
any suggestions?

do u think looking at output file with hex editor helps as far as wierd chars!

why/how are those wierd chars generated?

Can you show how the File object is being created? Does it already exist and perhaps read-only? Or maybe on a drive with no room left?

I recommend making a test program like I did and getting it working, so you can at least compare your code to it.

import java.io.*;
public class TestFileWrite
{

   public static void main(String[] args)
   {
      try {
         File outputfile = new File("testfile.txt");
         BufferedWriter out = new BufferedWriter(new FileWriter(outputfile));
              out.write("ITRS SYSTEM");
              out.newLine();
              out.write("    (ITRS)         ");
              out.newLine();
              out.write("    TEST SUBSYSTEM             ");
              out.newLine();
              out.flush();
              out.close();
          } catch (IOException e) {
              System.out.println("excpetion caught" + e);
              System.exit(1);
          }
   }
}
