Thread: FileWrite Over-Writing txt Files. D:

Is There anyway to prevent this from happening?

    File myFile = new File(username.getText() + ".txt");
    try {
 
        FileWriter fw = new FileWriter(myFile);
        PrintWriter pw = new PrintWriter(fw);
        pw.println("Username: " + username.getText());
        pw.println("Password: " + password.getText());
 
        pw.close();
 
    }   catch (FileNotFoundException e) {
            System.err.println("File not found: " + myFile);
    }   catch (Exception e) {
            e.printStackTrace();
    }

Use a different FileWriter constructor.

Yes, the FileWriter constructors that take a File or String arguments can all throw an IOException. The documentation I linked to explains when - eg you specify a directory rather than a file, or you don't have file write permissions etc.

This is over and above the FileNotFoundException which you are already dealing with. You have to deal with IOException as well.

At the moment you are catching a general Exception. If you want to deal specifically with the IOException, do so after FileNotFoundException because IOException is more general.

Or do you mean your program is throwing an IOException at runtime? If so, post the code you are currently using and the full stack trace.

What code are you using now?

Then my advice remains what it was: use an appropriate FileWriter consructor.

Did you read the documentation I linked to? Say if there's anything there that isn't clear. That form of the constructor will work with your current code because you are already catching Exception (which means basically anything that can go wrong.
