FileWriter error

**kthomp271828** · 11-29-2011, 05:13 AM

Hi. I have just experienced something new. I am reading multiple files from one directory and writing multiple files to another directory. The problem seems to be that, sometimes, one file is not finished writing before the next one is ready to start. This causes the previous files to be destroyed. If I put a Thread.sleep(timeToSleep) in there then it works fine .... but very slowly. What is the proper way to handle this so that the code finishes processing one before moving on to the next?

Java Code:

 input = "C:/pathToInput";	
		File myDir = new File(input);
		File[] files = myDir.listFiles();
		
		for(int i = 0; i < files.length; i++) {
			output = "C:/pathToOutput/user"+(i+1)+".txt";
			FileWriter w = new FileWriter(output);
			BufferedWriter out = new BufferedWriter(w);
			FileInputStream fstream = new FileInputStream(files[i]);
			DataInputStream in = new DataInputStream(fstream);
			BufferedReader br = new BufferedReader(new InputStreamReader(in));
			
			row = br.readLine();
			do stuff ...
			out.write(foobar);
			br.close();
			out.close();
		}

There's something else going on other than the code you've posted.
I do note you have no exception handling in there...

**kthomp271828** · 11-29-2011, 03:19 PM

Here is the entire code. As I said, I put the Thread.sleep() in there and it seemed to work fine but very slowly because of the pause each iteration. I let it run over night and came in this morning to happily see all the output files written to the directory (even opened some of them to make sure they had written correctly). Then, I changed directory (which for some reason was very slow also) and changed back. When I came back, lo and behold, only one of the files was still there. It just deleted all the rest of them. I am utterly confused ...

Java Code:

public void removeXML() throws IOException, InterruptedException {
		int j;
		String row, post;
		String[] posts;
		String input, output;
		
		input = "C:/pathToInput/";	
		File myDir = new File(input);
		File[] files = myDir.listFiles();
		output = "C:/pathToOutput/";
		
		for(int i = 0; i < files.length; i++) {
			FileWriter w = new FileWriter(output+"user"+(i+1)+".txt");
			BufferedWriter out = new BufferedWriter(w);
			FileInputStream fstream = new FileInputStream(files[i]);
			DataInputStream in = new DataInputStream(fstream);
			BufferedReader br = new BufferedReader(new InputStreamReader(in));
			br.readLine();	//skip line 1
			br.readLine();	//skip line 2
			row = br.readLine();	//all posts
			posts = row.split("<body>");
			for(int k = 1; k < posts.length; k++) {
				j = 0;
				post = "";
				while(posts[k].charAt(j) != '<') {
					post = post + posts[k].charAt(j);
					j++;
				}
				out.write(post+"\r\n");
			}
			br.close();
			out.close();
			Thread.sleep(500);
		}
	}

It just deleted all the rest of them

Do you mean deleted the files or deleted the contents of the files?

Where there any error messages on the console from the when the program executes?
Where does the execution go if an exception is thrown? Does that code print/write out a message that you can see? It should write out an error message so you can find the problem and fix it.

It deleted the actual files (except the very first one is still there). There were no error messages during execution. The program seemed to run fine and all of the files were in the output directory after the program finished executing until I changed directory and came back.

Without the Thread.sleep() in there, what seems to happen is that it writes a few files then deletes them, writes a few more, etc ...

**Norm** · 11-29-2011, 04:57 PM

The code you posted doesn't have any methods to delete files. Is there logic elsewhere in your code that does a delete?

When I ran a simple test with the code you posted, it created a file (I had one file in the input folder) but did not write any data in it.

The code as posted seems to do what it looks like it should do. Copy that code to a small simple program and execute it. Have no other logic in the program except what is shown in your post.
Use a small number of input files for testing.

Either your testing is incomplete or your observations of what the code does needs careful examination.

Actually, this is the whole program ... no other logic in the code. This is the main method (the constructor doesn't do anything):

Java Code:

public static void main(String[] args) throws IOException, InterruptedException {
		
		Extractor myExtractor = new Extractor();
		myExtractor.removeXML();
}

I just now let it produce a few output files (about 20 whereas, in the end, there are over 20,000). It wrote the 20 files. I opened them and verified that they wrote correctly. I went up a level in the directory, came back and only the first file was still there. :(
I am at a loss.

**Norm** · 11-29-2011, 05:10 PM

Sorry your posted code is missing the imports, the class definition and the main method.

I went up a level in the directory, came back and only the first file was still there.

What OS are you on? What other programs do you have running that can delete files when you are not looking?
Where is your little brother when this happens?

If you are viewing 20 files in a directory, change up a directory level and then come back to the same directory, I don't know how any of the files can be deleted unless there is a program executing that deletes them.

Can you capture this on a command prompt window and copy and paste it here so we can see the evidence?

**kthomp271828** · 11-29-2011, 05:24 PM

Haha, I wish it was just a little brother messing with me because then I could fix it. I just now went back and edited the previous post with the main method. Here is the whole thing:

Java Code:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.BufferedWriter;
import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;
import java.util.StringTokenizer; 

public class Extractor() {

     public void removeXML() throws IOException, InterruptedException {
          //see code above
     }
     public static void main(String[] args) throws IOException, InterruptedException {
         
           Extractor myExtractor = new Extractor();
           myExtractor.removeXML();
     }
}

I am running Windows 7, but not running any other code ...

**Norm** · 11-29-2011, 05:27 PM

Some things I see in your code that seem unusual:
the files must have at least three lines in them, only the third line is processed by the code, the fourth and following lines are not read.
If the third line is not properly configured, nothing is written to the output file.

The code you posted is NOT the whole thing.
Where is the Extractor class defined?

YOU ARE NOT EXECUTING THE METHOD YOU SHOW. You are executing code from another class!!!

**kthomp271828** · 11-29-2011, 05:38 PM

Oh sorry for the confusion ... I was changing the names to protect the innocent. This is the "Extractor" class ... I just forgot to take that extra word out of the class name before I posted it. :)
As for the file peculiarities, you are correct ... all of the file formats are homogeneous with exactly 3 lines. The only content that needs to extracted is in the third line.

**Norm** · 11-29-2011, 05:43 PM

I can't see any problems with the code you are posting.

I just forgot

What else have you forgotten to say about your problem? I lose interest when this happens.

Can you capture what happens on a command prompt window and copy and paste it here so we can see the evidence?

**kthomp271828** · 11-29-2011, 05:56 PM

Oh, it just became more interesting ... from the command prompt, I listed the files in the directory and it says they are all there. I was even able to open them from the command prompt. I went back to the Windows folder and it only showed the first file still. There were no hidden files or anything like that. It's weird ... but at least I know the files are there. I guess that solves it.

**Norm** · 11-29-2011, 05:58 PM

Can you capture what happens on a command prompt window and copy and paste it here so we can see the evidence?

To copy the contents of the command prompt window:
Click on Icon in upper left corner
Select Edit
Select 'Select All' - The selection will show
Click in upper left again
Select Edit and click 'Copy'

Paste here.

**kthomp271828** · 11-29-2011, 06:14 PM

Java Code:

C:\pathToOuput>ls

... lots of user files
user9997.txt
user9998.txt
user9999.txt

C:\pathToOutput>

After seeing this, I went back to the Windows folder and changed the "Arrange by" option then changed it back again (so it's the same as when I started). After that (oddly enough) all the files showed up in the Windows folder. Interestingly though, I went to another folder and came back again only to find that it once again is only listing the first file. So, it the end, it seems to be a Windows oddity and not a Java issue. Oh well, at least I know the files are there and I am able to access them. :) Thanks for your help.

**Norm** · 11-29-2011, 06:19 PM

Can you show the complete console for all your observations or is there a problem?
Your 8 line posting of the console is useless.
This is what I am looking for:
