 |
|
Hi all,
Just found this group, it may be appropriate for me as a newbie!
The following code cam straight from the book, but cannot find the file
"text.txt", My understanding is that it should be creating the file!!
Any ideas, Thanks, Jim
import java.io.*;
public class keytodisk
{
public static void main(String args[])
throws IOException
{
String str;
FileWriter fw;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
try
{
fw = new FileWriter("C:test.txt");
}
catch(IOException exc)
{
System.out.println("Cannot open file");
return;
}
System.out.println("Enter text ('stop' to quit).");
do
{
System.out.print(":");
str = br.readLine();
if (str.compareTo("stop") == 0) break;
str = str + "rn" ; //add new line
fw.write(str);
}
while(str.compareTo("stop") != 0);
fw.close();
}
}

Look at the API for FileWriter:
http://java.sun.com/j2se/1.4.1/docs/api/java/io/FileWriter.html
The second paragraph states that this type of auto-creation of files
is platform specific. To be safe, use the File object to test for the
files existence, and create a new file if needs be.

You used a '' in the file name string : "C:test.txt"
A '' is used for escape characters...
Either use a '/' or a double '\'!
