[RESOLVED] copying file from one directory to another

I have ComputerPlayerInterface.java in this folder:

C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\eg\ACS

and now i want to put it into here

C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\eg\submissions\msk9

could someone show me how to do that in java?

Copy it's content to the chosen path then delete it
