checking if a file exists.... 1

[Guest_imported]

Hey everyone,

I have a question regarding error checking with files. In my program, I create the file backUp.html (which I write to)..by doing so:

PrintWriter pw = new PrintWriter(new FileWriter("C:/Windows/Desktop/backUp.html&quot);

However, what if the file backUp.html already exists? I think it would be nice if I could prompt the user and ask him/her if he/she would like to overwrite the file before it automatically does so...!

Is there a way to do this?

Any feedback will be appreciated.

Thanks in advance,

J.Kamdar

Of course you can.

...
File f = new File("c:\windows\desktop\backup.html"
if (f.exists()) // check if file exists
// prompt user
...

Thanks...

I can still use that method even with PrintWriters? I will give it a try.

Thanks for the help.

Yes of course. Do the check before using your PrintWriter.
