This code will copy a web page to specified file on your hard drive.

Compile the code below and create a test.txt file on your C:\ directory. Then type the following on the command line.

java CopyURL http://www.ettasoft.com c:\test.txt

It will copy the web page to the test.txt file.

Also one last thing you will get a deprecation error on the toLocaleString but the code will still work. I have to change to DateFormat but have not had the time to update the code.
