If you sent that program as an attachment, you need to be aware
that this list does not allow attachments and all attachments are
stripped off before distribution to the list members.

Hi Rasha,
that`s easy. Just take the name as entered by the user and create a
new File out of this name, like this:
File testMe = new File( file_name);
This instance of the File class is just an object in memory, it does
not yet refer to any existing file. BUT: you can ask this File
instance whether a real thing with this name exists, namely by:
if (testMe .exists() && testMe .canRead())
// all right, file is there and can be read.
...
else
JOptionPane.showMessageDialog(null,"Sorry...but there is
something wrong with the file. Please check the source code file`s
name again.");
And the best way to make sure that this is done until a real file
name has been entered is a loop like this:
String fileName;
File testMe;
boolean fileIsOk;
do
{ fileName = JOptionPane .showInputDialog( "Please enter file name
plus extension.");
testMe = new File( fileName);
fileIsOk = testMe .exists() && testMe .canRead();
if ( ! fileIsOk)
JOptionPane .showMessageDialog( (null, "Sorry...but there is
something wrong with the file. Please check the source code file`s
name again.");
} while ( ! fileIsOk);
I haven`t tried this code, you should check for the return values of
the show...Dialog() functions because if I recall correctly
showInputDialog() returns something else if you click Abort in the
entry form. But the general outline above should do the trick.
Regards,
Nico
