The most likely cause is that you don't have the classpath variable set properly.

To fix this, do the following:

1) Go to 'my computer' and right click and select 'properties'. Then under the advanced tab, select 'enviromment variables'.

2) In there if you see a 'classpath' variable, edit that entry to reflect a dot (.) following what already is in there. (eg: classpath=<a series of paths seperated by colons>;. ) <- Note I inserted a dot after teh last colon.

This should fix your problem

its not a softyware problem
its programatic error

be sure the filename is same as the public class name

[.nxto.]

Make sure your PUBLIC class name (if you have more than one class in your program) is the same as the file name. Also, make sure you don't have a semicolon at the end of the public class definenition line. Finally, make sure you have matching braces in all the appropriate places.
