Thread: Suggestion to declare variable that is declared

The following simple clock of code won't work, and the reason I am getting is that it has reached the end of file while parsing, but if I add another }, it comes back saying it is unnecessary??

package filez;
import java.io.*;
public class Filez{
public static void main(String[] args){
File f = new File("test.txt");
try(
FileWriter fw = new FileWriter(f); 
fw.write("write this to file"); //Keeps saying identifier expected????
fw.close();}catch(Exception ex){}
}// This is the final closing bracket, but it is saying I reached end of file while parsing????

This code is an exact duplication of code that a friend of mine wrote that works without a hitch, so I don't get this.
What is wrong with the line, fw.write("write this to file");??
I mean I declared fw in the previous line, FileWriter fw = new FileWriter(f);, so I don't see the issue here????
Can someone PLEASE tell me what is happening here????

It uses a ( instead of a { after the try.

BTW The posted code is poorly formatted making it hard to read and understand. Nested statements need to be indented.

I apologize for the lazy formatting of my code, but I am writing this in notepad, and it is tiresome to keep indenting everything properly sometimes.
So, if I am reading what you are saying here correctly, I need to use (, instead of { after try??

Please read this: The try-with-resources Statement (The Java™ Tutorials > Essential Classes > Exceptions)

You are using syntax that is halfway between a normal try block and a try-with-resources block, and we don't know which one you're actually trying to do.

I am actually not truly adept at using exception handling in my code, so you could be exactly correct that I have misused the try catch block. Also, I write relatively small, simple programs generally, so indentation has not really been an issue for me, that is until I get a strange error that I do not agree with. So, I will go ahead and concentrate on proper indentation for even the smallest programs from here forward. Thanks for the advice, and the suggestions!!
