Curious about some Java out.Write output

When I run the following code:

int i = 0

 try {
        fstream = new FileWriter(filename);
        BufferedWriter out = new BufferedWriter(fstream);
while (i < 100) {
            out.write("My Name is Bobby Bob");
            out.writ开发者_JAVA技巧e(i);
            out.newLine();
            i++;
}
        out.flush();
        out.close();
    } catch (IOException e) {
        e.getClass();
    }

I get the following in my output file:

My Name is Bobby Bob 

x100

each one is followed by a weird symbol. Male sign, female sign etc etc.

My question is and its more of a curious one. What causes these weird symbols to appear? I was expecting numbers as it counted up. Where are these symbols pulled from?

out is a RandomAccessFile ?

I think you are using write(byte) instead of write(String), so you are writting the byte X, see ASCII TABLES for representations.

Try

write(""+i);

Looking at BufferedWriter java api:

http://download.oracle.com/javase/1.4.2/docs/api/java/io/BufferedWriter.html#write(int)

it says that it writes the integer representation of a char, for your understanding.

If you want to print the value 0 you have to write 48 as this image represents:

---

When you write

out.write(i);

it writes the (char) i not the number in i as text.

If you want to write i as a number use print

out.print(i);

or

out.write(String.valueOf(i));

or

out.write(""+i);

---

It looks like you are writing single characters that are specified by the given int value, and not a character representation of the variable i.

System.out is a PrintStream. The PrintStream.write(int) method writes a single byte to the output stream with the byte value specified. So you're not writing the integers 0 through 100, you're writing the bytes 0 through 100. You probably want print(int) instead of write(int).
