You need to realise that there is a difference between creating a File object, which is what the constructor does, and creating an actual File on your computer.
Very simply, if I write:

    File myFile = new File("sample.txt");

I now have a file object in memory which will eventually 'represent' a file on the hard disc. This is the file "instance" you mention. I can now check to see if there already is a file of this name by using "if (myFile.exists())...". I can create an actual file on the hard disc by calling:

    myFile.createNewFile();

Now the picture is complete. We have an instance of the File class in memory which is acting as a proxy for the real file on disc. If You now create, say a FileWriter passing this File object to the constructor, you can now start writing to the real file.

Hope that helps.

Mark, that helps A LOT, thank you..  this is precisely the kind of
explanation I needed, it's very clear now..  create File Obj then
pass this File Obj to constructor when creating the file...

:)  thanks again....  Frances
