why does this not work? >:(

[Eric Johnson]

i am a newbie tryin to learn the language. i am messing with writing files and can't get it to work. here is what i tried, not knowing what i was doing but looking over the api and trying to go from there:

<font size=2.5>
import java.io.*;
public class WriteTest {
public static void main(String[] args) {
File testFile = new File(args[0] + ".txt");
try {
testFile.createNewFile();
FileWriter toWrite = new FileWriter(testFile);
toWrite.write(args[1]);
} catch (IOException x) {
}
}
}

it creates a text file, but without any contents. ok, so before i get too frustrated with this i decide to look in the book from my class, and try the code there. it doesn't work either. it creates an empty file also.
this is from sun's java programming language class sl-275:

<font size=2.5>
import java.io.*;
public class WriteFile {
public static void main (String[] args) {
File file = new File(args[0]);
try {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
PrintWriter out = new PrintWriter(new FileWriter(file));
String s;
System.out.print("Enter file text. ");
System.out.println("[Type ctrl-d to stop.]");
while ((s = in.readLine()) != null) {
out.println(s);
}
in.close();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

why can i not write a file that actually contains something? please help, i am becoming disillusioned.

Just add a line
toWrite.flush();
after you do your write().

THANK YOU! that's what i get for ignoring methods i don't think i will have to bother with.
i imagine adding toWrite.close() will do the trick also. i'm not sure what the difference is, but i will research it. thanx again, i don't feel so dumb now. oh, and thanx for formatting the code. i will try and do that in the future.
