Question

I am trying to write a single character in a text file.

I do:

  BufferedWriter out = new BufferedWriter(new FileWriter("exemple.txt"));
  out.write((char)174);
  out.close();

My text file is supposed to contains 10101110, if I look it with a binary viewer. Instead of it, it shows 11000010 10101110. So it writes 194 174, which is not the expected result.

So how can I write a single character in java which will result the good binary value ?

Answer 1

You need to open the file using the appropriate character set. something like:

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("c:\\exemple.txt"), "CP1252"));

i would suggest reading a good tutorial which teaches the difference between bytes and chars and what a character set is.
