writeChras() problem

[satellite03]

import java.io.*;

class RAFtest
{
public static void main(String args[]) throws IOException
{
RandomAccessFile  f  = new  RandomAccessFile("c:\\abc.txt","rw");
BufferedReader abc = new BufferedReader(new FileReader("c:\\def.txt"));
String s = abc.readLine();
f.writeChars(s);
}
}

def.txt
_______
abcd



output in abc.txt
__________________
a b c d // note the gaps in between chars


why there are gaps ? if i usued writeBytes() there would have been no gaps.
how those gaps have been created in the output?

writeChars() writes the letters in Unicode instead of Ascii, so it takes two bytes per character.

can you tell the mechanism how it is written ?

is it like, first it will read 'a' then write 'a' and put a gap ? right ?

things are messy here.i dont understand the way it is processing.


thanks

It reads the a which to originally was ASCII and writes it as Unicode, using two bytes. In order not to have the space, you need to use writeBytes().
